Texas Instruments Inc. (TXN), known as TI , is an American company based in Dallas, Texas, United States, which develops and commercializes semiconductor and computer technology. TI is the third largest manufacturer of semiconductors worldwide after Intel and Samsung, the second largest supplier of chips for cellular handsets after Qualcomm, and the largest producer of digital signal processors (DSPs) and analog semiconductors, among a wide range of other semiconductor products, including calculators, microcontrollers and multi-core processors.
Texas Instruments was founded in 1951. It emerged after a reorganization of Geophysical Service. This company manufactured equipment for use in the seismic industry as well as defense electronics. TI researched infrared technology in the late 1950s and later made transistors, including the world's first workable silicon transistor, radar systems, guidance and control systems for both missiles and bombs. In 1954, Texas Instruments designed and manufactured the first transistor radio and Jack Kilby invented the integrated circuit in 1958 while working at TI's Central Research Labs. The company produced the first integrated circuit-based computer for the U.S. Air Force in 1961. The hand-held calculator was introduced to the world by TI in 1967.
In the 1970s and 80s the company focused on consumer electronics including digital clocks, watches, home computers as wells as various sensors. In 1997, its defense business was sold to Raytheon. In 2007, Texas Instruments was awarded the Manufacturer of the Year for Global Supply Chain Excellence by World Trade magazine. Texas Instruments is considered to be one of the most ethical companies in the world.
After the acquisition of National Semiconductor in 2011, the company has a combined portfolio of nearly 45,000 analog products and customer design tools, making it the world's largest maker of analog technology components. In 2011, Texas Instruments ranked 175 in the Fortune 500. TI is made up of two main divisions: Semiconductors (SC) and Educational Technology (ET) of which Semiconductor products account for approximately 96 % of TI's revenue.
