Product Description:

Pericom Semiconductor’s PI74FCT series of logic circuits are pro-

duced 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.
