Product Description
Pericom Semiconductor’s PI74FCT3 series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74FCT3245 is an 8-bit bidirectional transceiver designed
for asynchronous two-way communication between data buses.
The transmit/receive input pin (T/R) determines the direction of
data flow through the bidirectional transceiver. Transmit (active
HIGH) enables data from A ports to B ports, and receive (active
LOW) from B ports to A ports. The output enable (OE) input, when
HIGH, disables both A and B ports by placing them in HIGH Z
condition.
The PI74FCT3245 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3V/5.0V system.
