Product Description
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced using the Company’s advanced 0.6/0.8 micron CMOS
technology, achieving industry leading speed grades. All
PI74FCT2XXX devices have a built-in 25 Ohm series resistor on all
outputs to reduce noise because of reflections, thus eliminating the
need for an external terminating resistor.
The PI74FCT245T/640T/645T and PI74FCT2245T/2640T/2645T are
8-bit wide octal buffer bidirectional transceivers designed for
asynchronous two-way communication between data buses. The
transmit/receive (T/R) input 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.

FCT245, 2245, 645, 2645 are non-inverting options.
FCT640 & FCT2640 are inverting options.
H = High Voltage Level, X = Don't Care, L = Low
Voltage Level, Z = High Impedance
640 is inverting from input to output.
