Product Description:
Pericom Semiconductor's PI74FCT series of logic circuits are produced in the Company's advanced 0.8 micron CMOS technology, achieving industry leading speed grades. These are high-speed two independent 1-of-4 decoders. Each decoder accepts two binary weighted inputs (A0, A1) and gives four mutually exclusive active LOW outputs (O0-O3: PI74FCT139T) or active HIGH outputs (O0-O3: PI74FCT239T). There is one active LOW enable (E) for each decoder. For the PI74FCT139T all outputs are forced HIGH, and for the PI74FCT239T all outputs are forced LOW when E is HIGH.
