Logic Block Diagram
Product Description
Pericom Semiconductors PI74FCT series of logic circuits are
produced using the Companys 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.
Product Features
PI74FCT245/640/645T and PI74FCT2245/2640T/2645T are pin
compatible with bipolar FAST Series at a higher speed and
lower power consumption
25 Ohm series resistor on all outputs (FCT2XXX only)
TTL input and output levels
Low ground bounce outputs
Extremely low static power
Hysteresis on all inputs
Industrial operating temperature range: 40°C to +85°C
