Description
Pericom Semiconductor’s PI74FCT245T and PI74FCT2245T 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
throughthebidirectionaltransceiver.Transmit(activeHIGH)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 Hi-Z condition.
PI74FCT2245T has 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.
Features
Pin compatible with bipolar FAST Series at a higher speed
and lower power consumption
25-ohm series resistor on all outputs (FCT2245Tonly)
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
Packaging (Pb-free & Green Available):
