Texas Instruments

Texas Instruments Incorporated (TI) is an American multinational semiconductor company headquartered in Dallas, Texas. It is one of the top 10 semiconductor companies worldwide based on sales volume. The company's focus is on developing analog chips and embedded processors, which account for more than 80% of its revenue. TI also produces digital light processing (DLP) technology and education technology products including calculators, microcontrollers, and multi-core processors. Texas Instruments emerged in 1951 from the reorganization of Geophysical Service Incorporated, a company founded in 1930 that manufactured equipment for the seismic industry and defense electronics. TI produced the world's first commercial silicon transistor in 1954, and the same year designed and manufactured the first transistor radio. Jack Kilby invented the integrated circuit in 1958 while working at TI's Central Research Labs. TI also invented the handheld calculator in 1967 and introduced the first single-chip microcontroller in 1970, combining all the elements of computing onto a single chip. In 1987, TI invented the digital light processing device (also known as the DLP chip), which serves as the foundation for the company's DLP technology and DLP Cinema. TI released the popular TI-81 calculator in 1990, which made it a leader in the graphing calculator industry. Its defense business was sold to Raytheon Company in 1997, allowing TI to strengthen its focus on digital solutions. After the acquisition of National Semiconductor in 2011, the company had a combined portfolio of 45,000 analog products and customer design tools.
