Signetics, a contraction of Signal Network Electronics, was founded in 1961 in Mountain View, California by former Fairchild
employees David Allison, David James, Lionel Kartner and Mark Weisenstein. It was the first company in the world established
expressly to make and sell integrated circuits (IC). Within a year of its founding, the company's first family of bipolar
digital diode transistor logic circuits had gained market acceptance and were finding initial application in military and
space systems. Signetics was the first IC company to receive both Minuteman approval (1967) and NASA line certification 1970).
Among the company's early innovations were the 555 timer, Dolby circuits, and the programmable read-only memory.
