Product Description
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74FCT163245 is a 16-bit bidirectional transceiver designed
for asynchronous two-way communication between data buses.
The direction control input pin (xDIR) determines the direction of
data flow through the bidirectional transceiver. The Direction and
Output Enable controls are designed to operate this device as either
two independent 8-bit transceivers or one 16-bit transceiver. The
output enable (xOE) input, when HIGH, disables both A and B
ports by placing them in HIGH Z condition.
