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 PI74FCT860T series bus transceivers provide highperformance 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. The PI74FCT861T is a 10-bit non-inverting bus transceiver. The PI74FCT863T is a 9-bit non-inverting option of the PI74FCT864T 9-bit inverting bus transceiver.
