This integrated circuit was produced in about 1960 by Fairchild Semiconductor. It is a bistable RS (Reset/Set) Flip-Flop constructed using four NPN bipolar transistors and two resistors diffused into a single monolithic chip of silicon. The maximum operating clock speed is 1 megahertz and the delay is 50 nanoseconds.
