Texas Instruments Inc. (TI) is an American technology company that
designs and manufactures semiconductors and various integrated
circuits, which it sells to electronics designers and manufacturers
globally. Headquartered in Dallas, Texas, United States, TI is one
of the top ten semiconductor companies worldwide, based on sales
volume. Texas Instruments's focus is on developing analog chips and
embedded processors, which accounts for more than 85% of their
revenue. TI also produces TI digital light processing (DLP)
technology and education technology products including calculators,
microcontrollers and multi-core processors. To date, TI has more than
43,000 patents worldwide.
Texas Instruments emerged in 1951 after a reorganization of
Geophysical Service Incorporated, a company founded in 1930 that
manufactured equipment for use in the seismic industry, as well as
defense electronics. TI produced the world's first commercial
silicon transistor in 1954, and designed and manufactured the first
transistor radio in 1954.
Jack Kilby invented the integrated circuit
in 1958 while working at TI's Central Research Labs. TI also invented
the hand-held calculator in 1967, and introduced the first single-chip
microcontroller (MCU) in 1970, which combined all the elements of
computing onto one piece of silicon.
In 1987, TI invented the digital light processing device (also known
as the DLP chip), which serves as the foundation for the company's
award-winning DLP technology and DLP Cinema. In 1990, TI came out
with the popular
TI-81 calculator which made them a leader in the
graphing calculator industry. In 1997, its defense business was sold
to Raytheon, which allowed TI to strengthen its focus on digital
solutions. After the acquisition of National
2011, the company had a combined portfolio of nearly 45,000 analog
products and customer design tools, making it the world's largest
maker of analog technology components.

Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson,
Eugene McDermott, and
Patrick E. Haggerty in 1951. McDermott was one
of the original founders of Geophysical Service Inc. (GSI) in 1930.
McDermott, Green, and Jonsson were GSI employees who purchased the
company in 1941. In November, 1945, Patrick Haggerty was hired as
general manager of the Laboratory and Manufacturing (L&M)
division, which focused on electronic equipment. By 1951, the
L&M division, with its defense contracts, was growing faster than
GSI's Geophysical division. The company was reorganized and initially
renamed General Instruments Inc. Because there already existed a firm
named General Instrument, the company was renamed Texas Instruments
that same year. From 1956 to 1961,
Fred Agnich of Dallas, later a
Republican member of the Texas House of Representatives, was the Texas
Instruments president. Geophysical Service, Inc. became a subsidiary
of Texas Instruments. Early in 1988 most of GSI was sold to the

Texas Instruments Statement of Purpose
Geophysical Service Incorporated
J. Clarence Karcher and
Eugene McDermott founded Geophysical
Service, an early provider of seismic exploration services to the
petroleum industry. In 1939, the company reorganized as Coronado
Corp., an oil company with Geophysical Service Inc (GSI), now as a
subsidiary. On December 6, 1941, McDermott along with three other GSI
employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased
GSI. During World War II, GSI expanded their services to include
electronics for the U.S. Army, Signal Corps, and the U.S. Navy. In
1951, the company changed its name to Texas Instruments, with GSI
becoming a wholly owned subsidiary of the new company.
An early success story for TI-GSI came in 1965 when GSI was able
(under a Top Secret government contract) to monitor the Soviet Union's
underground nuclear weapons testing under the ocean in Vela Uniform, a
subset of Project Vela, to verify compliance of the Partial Nuclear
Test Ban Treaty.
Texas Instruments also continued to manufacture equipment for use in
the seismic industry, and GSI continued to provide seismic services.
After selling (and repurchasing) GSI, TI finally sold the company to
Halliburton in 1988, at which point GSI ceased to exist as a separate
In early 1952,
Texas Instruments purchased a patent license to produce
germanium transistors from Western Electric Co., the manufacturing arm
of AT&T, for $25,000, beginning production by the end of the
On January 1, 1953, Haggerty brought
Gordon Teal to the company as a
research director. Gordon brought with him his expertise in growing
semiconductor crystals. Teal's first assignment was to organize what
became TI's Central Research Laboratories (CRL), which Teal based on
his prior experience at Bell Labs.
Among his new hires was
Willis Adcock who joined TI early in 1953.
Adcock, who like Teal was a physical chemist, began leading a small
research group focused on the task of fabricating "grown-junction
silicon single-crystal small-signal transistors. Adcock later became
the first TI Principal Fellow.
First silicon transistor and integrated circuits
Transistorized "logic" chip, an integrated circuit produced by TI
In January 1954
Morris Tanenbaum at
Bell Labs created the first
workable silicon transistor. This work was reported in the spring
of 1954, at the IRE off-the-record conference on Solid State Devices,
and was later published in the Journal of Applied Physics. Working
independently in April 1954,
Gordon Teal at TI created the first
commercial silicon transistor and tested it on April 14, 1954. On May
10, 1954, at the Institute of Radio Engineers (IRE) National
Conference on Airborne
Electronics in Dayton, OH,Teal presented a
paper: "Some Recent Developments in
Texas Instruments designed and manufactured the first
transistor radio. The
Regency TR-1 used germanium transistors, as
silicon transistors were much more expensive at the time. This was an
effort by Haggerty to increase market demand for transistors.
Jack Kilby, an employee at TI's Central Research Labs, invented the
integrated circuit in 1958. Kilby recorded his initial ideas
concerning the integrated circuit in July 1958, and successfully
demonstrated the world's first working integrated circuit on September
12, 1958. Six months later,
Robert Noyce of Fairchild
Semiconductor (who went on to co-found Intel) independently developed
the integrated circuit with integrated interconnect, and is also
considered an inventor of the integrated circuit. In 1969, Kilby
was awarded the National Medal of Science, and in 1982 he was inducted
into the National Inventor's Hall of Fame. Kilby also won the 2000
Nobel Prize in Physics for his part of the invention of the integrated
circuit. Noyce's chip, made at Fairchild, was made of silicon,
while Kilby's chip was made of germanium. In 2008, TI named its new
development laboratory "Kilby Labs" after Jack Kilby.
In 2011, Intel, Samsung, LG, ST-Ericsson, Huawei's HiSilicon
Technologies subsidiary, Via Telecom and three other undisclosed
chipmakers licensed the C2C link specification developed by Arteris
Inc. and Texas Instruments.

Texas Instruments Speak & Spell using a
TMC0280 speech synthesizer
TI-30 electronic calculator, 1976
7400 series of transistor-transistor logic (TTL) chips, developed
Texas Instruments in the 1960s, popularized the use of integrated
circuits in computer logic. The military grade version of this was the
Texas Instruments invented the hand-held calculator (a prototype
called "Cal Tech") in 1967 and the single-chip microcomputer in 1971,
was assigned the first patent on a single-chip microprocessor
(invented by Gary Boone) on September 4, 1973. This was disputed
by Gilbert Hyatt, formerly of the Micro Computer Company, in August
1990 when he was awarded a patent superseding TI's. This was
over-turned on June 19, 1996 in favor of TI (note:
usually given credit with
Texas Instruments for the
almost-simultaneous invention of the microprocessor).
First speech synthesis chip
Texas Instruments introduced the first single-chip LPC speech
synthesizer. In 1976 TI began a feasibility study memory intensive
applications for bubble memory then being developed. They soon focused
on speech applications. This resulted in the development the TMC0280
one-chip linear predictive coding (LPC) speech synthesizer which was
the first time a single silicon chip had electronically replicated the
human voice. This was used in several TI commercial products
beginning with Speak & Spell which was introduced at the Summer
Electronics Show in June 1978. In 2001 TI left the speech
synthesis business, selling it to Sensory Inc. of Santa Clara,
Consumer electronics and computers
In May 1954,
Texas Instruments designed and built a prototype of the
world's first transistor radio, and, through a partnership with
Industrial Development Engineering Associates (I.D.E.A.) of
Indianapolis, Indiana, the 100% solid-state radio was sold to the
public beginning in October of that year.
In 1973, the handheld calculator SR-10 (named after slide rule) and in
1974 the handheld scientific calculator SR-50 were issued by TI. Both
had red LED-segments-numeric displays. The optical design of the SR-50
is somewhat similar to the
HP-35 edited by Hewlett Packard before in
early 1972, but buttons for the operations "+", "–", ... are in the
right of the number block and the decimal point lies between two
TI continued to be active in the consumer electronics market through
the 1970s and 1980s. Early on, this also included two digital clock
models; one for desk, and the other a bedside alarm. From this sprang
what became the Time Products Division, which made LED watches. Though
these LED watches enjoyed early commercial success thanks to excellent
quality, it was short lived due to poor battery life. LEDs were
replaced with LCD watches for a short time, but these could not
compete because of styling issues, excessive makes and models, and
price points. The watches were manufactured in
Dallas and then
Lubbock, Texas. In 1978,
Texas Instruments introduced the first
single-chip speech synthesizer, and incorporated it in a product
called Speak & Spell, which was later featured in the movie E.T.
the Extra-Terrestrial. Several spin-offs, such as the Speak & Read
and Speak & Math, were introduced soon thereafter.
In 1979, TI entered the home computer market with the TI-99/4, a
competitor to such entries as the Apple II, Tandy/Radio Shack TRS-80
and the later
Atari 400/800 series and Commodore VIC-20. It
discontinued the TI-99/4A (1981), the sequel to the 99/4, in late 1983
amidst an intense price war waged primarily against Commodore. At the
1983 Winter CES, TI showed models 99/2 and the Compact Computer 40
(CC-40), the latter aimed at professional users. The TI Professional
(1983) ultimately joined the ranks of the many unsuccessful
x86-based—but non-compatible—competitors to the
IBM PC (the
founders of Compaq, an early leader in PC compatibles, all came from
TI). The company for years successfully made and sold PC-compatible
laptops before withdrawing from the market and selling its product
line to Acer in 1998.
Texas Instruments operated this
Convair 240 on experimental work in
the 1980s fitted with a modified extended nose section
Texas Instruments entered the defense electronics market in 1942 with
submarine detection equipment, based on the seismic exploration
technology previously developed for the oil industry. The division
responsible for these products was known at different points in time
as the Laboratory & Manufacturing Division, the Apparatus
Division, the Equipment Group and the Defense Systems &
Electronics Group (DSEG).
During the early 1980s,
Texas Instruments instituted a quality program
which included Juran training, as well as promoting statistical
Taguchi methods and Design for Six Sigma. In the late
'80s, the company, along with
Eastman Kodak and Allied Signal, began
Motorola institutionalizing Motorola's Six Sigma
methodology. Motorola, who originally developed the Six Sigma
methodology, began this work in 1982. In 1992, the DSEG division of
Texas Instruments' quality improvement efforts were rewarded by
Malcolm Baldrige National Quality Award for manufacturing.
Infrared and radar systems
TI developed the AAA-4 infra-red search and track (IRST) in the late
50's and early 60's for the F-4B Phantom for passive scanning of
jet engine emissions but possessed limited capabilities and was
eliminated on F-4D's and later models.
In 1956, TI began research on infrared technology that led to several
line scanner contracts and with the addition of a second scan mirror
the invention of the first forward looking infrared (FLIR) in 1963
with production beginning in 1966. In 1972 TI invented the Common
Module FLIR concept, greatly reducing cost and allowing reuse of
TI went on to produce side-looking radar systems, the first terrain
following radar and surveillance radar systems for both the military
and FAA. TI demonstrated the first solid-state radar called Molecular
Electronics for Radar Applications (MERA). In 1976 TI developed a
microwave landing system prototype. In 1984 TI developed the first
inverse synthetic aperture radar (ISAR). The first single-chip gallium
arsenide radar module was developed. In 1991 the Military Microwave
Integrated Circuit (MIMIC) program was initiated – a joint
effort with Raytheon.
Missiles and laser-guided bombs
In 1961, TI won the guidance and control system contract for the
AGM-45 Shrike anti-radiation missile. This led
later to the prime on the High-speed Anti-Radiation Missile (AGM-88
HARM) development contract in 1974 and production in 1981.
In 1964, TI began development of the first laser guidance system for
precision-guided munitions (PGM) leading to the
Paveway series of
laser-guided bombs (LGBs). The first LGB was the BOLT-117.
In 1969, TI won the Harpoon (missile) Seeker contract. In 1986 TI won
FGM-148 Javelin fire-and-forget man portable anti-tank guided
missile in a joint venture with Martin Marietta. In 1991 TI was
awarded the contract for the
AGM-154 Joint Standoff Weapon
AGM-154 Joint Standoff Weapon (JSOW).

Because of TI's research and development of military temperature range
silicon transistors and integrated circuits (ICs), TI won contracts
for the first IC-based computer for the U.S. Air Force in 1961
(Molecular Electronic Computer) and for ICs for the Minuteman
Missile the following year. In 1968, TI developed the data systems for
Mariner Program. In 1991 TI won the F-22 Radar and Computer
Divestiture to Raytheon
As the defense industry consolidated, TI sold its defense business to
Raytheon in 1997 for $2.95 billion. The Department of Justice required
Raytheon divest the TI Monolithic Microwave Integrated Circuit
(MMIC) operations after closing the transaction. The TI MMIC
business accounted for less than $40 million in 1996 revenues, or
roughly two percent of the $1.8 billion in total TI defense revenues
was sold to TriQuint Semiconductor, Inc.
Raytheon retained its own
MMIC capabilities and has the right to license TI's MMIC
technology for use in future product applications from TriQuint.
Raytheon acquired TI DSEG,
Raytheon then acquired Hughes
Aircraft from General Motors.
Raytheon then owned TI's mercury cadmium
telluride detector business and
Infrared (IR) systems group. In
California, it also had Hughes infrared detector and an IR systems
business. When again the US government forced
Raytheon to divest
itself of a duplicate capability, the company kept the TI IR systems
business and the Hughes detector business. As a result of these
acquisitions these former arch rivals of TI systems and Hughes
detectors work together.
Immediately after acquisition, DSEG was known as
Raytheon TI Systems
(RTIS). It is now fully integrated into
Raytheon and this
designation no longer exists.
Texas Instruments was active in the 1980s, in the area of artificial
intelligence. In addition to ongoing developments in speech and signal
processing and recognition, it developed and sold the Explorer
computer family of Lisp machines. For the Explorer a special 32-bit
Lisp microprocessor was developed, which was used in the Explorer II
and the TI MicroExplorer (a Lisp Machine on a
NuBus board for the
Apple Macintosh). AI application software developed by TI for the
Explorer included the Gate Assignment system for United Airlines,
described as "an artificial intelligence program that captures the
combined experience and knowledge of a half-dozen United operations
experts." In software for the PC, they introduced "Personal
Consultant" a rule-based expert system development tool and runtime
engine, followed by "Personal Consultant Plus" written in the
Lisp-like language from MIT known as Scheme, and the natural language
menu system NLMenu.
Sensors and controls
Texas Instruments was a major OEM of sensor, control, protection, and
RFID products for the automotive, appliance, aircraft, and other
industries. The S&C division was headquartered in Attleboro,
In 2006, Bain Capital LLC, a private equity firm, purchased the
Sensors & Controls division for $3.0 billion in cash. The RFID
portion of the division remained part of TI, transferring to the
Application Specific Products business unit of the Semiconductor
division, with the newly formed independent company based in Attleboro
taking the name Sensata Technologies.
TI sold its software division along with its main product such as the
Sterling Software in 1997. It is now part of Computer
Associates. TI still owns small pieces of software though such as the
software for calculators like TI Interactive!. TI also creates a
significant amount of target software for its digital signal
processors, along with host-based tools for creating DSP
TI store (eCommerce)
In 2000, a team at TI had a desire to sell Code Composer Studio
software to customers via the internet. In response, an employee
bought an off-the-shelf program and built an eCommerce platform over
the course of one weekend – the result was TI store. During
the same year, a separate online integrated circuit (IC) sample
ordering system was launched to replace a physical room where orders
were received via phone, fax, and email and then fulfilled by hand.
In 2002, the TI store inventory was expanded to include paid
evaluation modules (EVMs) and a separate home-grown online evaluation
module sample system was launched. This resulted in 3 separate
eCommerce systems for TI: one for paid evaluation modules, one for
sample evaluation modules, and one for sample integrated circuits.
In 2010, the TI store was completely redesigned using a new online
platform. Additionally, sample evaluation modules were moved into the
eStore from the home-grown application.
In 2014, at the TI store: integrated circuit samples were moved into
the store from the home-grown application and integrated circuit
purchase options were added. These changes combined all evaluation and
development modules, integrated circuits, and sample programs into one

On August 6, 1999,
Texas Instruments Inc. announced the restatement of
its results for parts of 1998 and the first quarter of 1999 after a
review by the Securities & Exchange Commission over the timing of
charges for a plant closing and writedown.
Today, TI is made up of four divisions: analog products, embedded
processors (EP), digital light processing (DLP), and educational
Analog products connect the physical and the digital worlds –
turning signals like sound, pressure, temperature, humidity and light
into digital 1s and 0s to be used by electronic devices – and
translating that data back to information we interact with in the real
world. These chips, including data converters, power management and
other devices, can extend and optimize battery life, improve accuracy,
sense conditions like humidity and temperature and much more.
Texas Instrument's analog integrated circuit portfolio includes both
power management and signal chain devices, as well as integrated
analog device and application solutions.
TI's subdivision power management includes the following product
Battery Management which encompasses innovative power products and
tools enable longer lasting and safer battery power designs. Some
example products include:

Texas Instruments maintains several lines of signal chain product
categories. The categories are as follows:
Amplifiers and Linear
Clock and Timing
Switches and Multiplexers
Embedded processing (EP)
Embedded processors are the processing brains of electronics that
gather inputs from analog chips and perform computational processing
to operate a system. Embedded processors can be low power and enable
long battery life or energy efficient products, or they can be high
performance to allow complex analytics systems or systems with high
computational throughput and everything in between. Also included are
wireless connectivity products that enable connectivity and help to
bring life to the Internet of Things.

Digital Light Processing
Digital Light Processing (DLP) is a trademark under which Texas
Instruments sells technology regarding TVs, video projectors and
digital cinema. On February 2, 2000, Philippe Binant, technical
manager of Digital Cinema Project at Gaumont in France, realized the
first digital cinema projection in Europe with the DLP CINEMA
technology developed by TI. DLP technology enables a diverse range of
display and advanced light control applications spanning industrial,
enterprise, automotive and consumer market segments.

Texas Instruments produces a range of calculators, with the TI-30
being one of the most popular early calculators. TI has also developed
a line of graphing calculators, the first being the TI-81, and most
popular being the
TI-83 Plus (with the
TI-84 Plus being an updated
There are many TI calculators still selling without graphing
TI-30 has been replaced by the TI-30X IIS. There
are some financial calculators for sale on the TI website.
In 2007, TI released the
TI-Nspire family of calculators, as well as
computer software that has similar capabilities to the calculators.
Texas Instruments calculator community
In the 1990s, with the advent of TI's graphing calculator series,
programming became popular among some students. The TI-8x series of
calculators (beginning with the TI-81) came with a built-in BASIC
interpreter, through which simple programs could be created. The TI-85
was the first TI calculator to allow assembly programming (via a shell
called "ZShell"), and the
TI-83 was the first in the series to receive
native assembly. While the earlier
BASIC programs were relatively
simple applications or small games, the modern assembly-based programs
rival what one might find on a
Game Boy or PDA.
Around the same time that these programs were first being written,
personal web pages were becoming popular (through services such as
Angelfire and GeoCities), and programmers began creating websites to
host their work, along with tutorials and other calculator-relevant
information. This led to the formation of TI calculator webrings and
eventually a few large communities, including the now-defunct TI-Files
and still-active ticalc.org.
The TI community reached the height of its popularity in the early
2000s, with new websites and programming groups being started almost
daily. In fact, the aforementioned community sites were exploding with
activity, with close to 100 programs being uploaded daily by users of
the sites. There was also a competition between both sites to be the
top site in the community, which helped increase interest and activity
in the community.
One of the common unifying forces that has united the community over
the years has been the rather contentious relationship with Texas
Instruments regarding control over its graphing calculators. TI
graphing calculators generally fall into two distinct groups: those
powered by the
Zilog Z80 and those running on the
series. Both lines of calculators are locked by TI with checks in the
hardware and through the signing of software to disable use of custom
flash applications and operating systems.
However, users employed the general number field sieve to find the
keys and publish them in 2009. TI responded by sending invalid DMCA
takedown notices, causing the
Texas Instruments signing key
controversy. Enthusiasts had already been creating their own operating
systems before the finding of the keys, which could be installed with
