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.

The PI74FCT286T bus transceiver provides high-performance bus

interface buffering for wide data/address paths carrying parity.

They are designed for high-capacitance load drive capability while

providing bus loading at both inputs and outputs.
