PI74FCT245T

PI74FCT2245T (25Ω Series)

Fast CMOS Octal Bidirectional Transceivers

Description

Features

• Pin compatible with bipolar FAST™ Series at a higher speed

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

datafromAportstoBports, andreceive(activeLOW)fromBports

toAports.Theoutputenable(OE)input,whenHIGH,disablesboth

A and B ports by placing them in Hi-Z condition.

and lower power consumption

• 25-ohm series resistor on all outputs (FCT2245Tonly)

• TTL input and output levels

• Low ground bounce outputs

• Extremelylowstaticpower

• Hysteresis on all inputs

• Industrial operating temperature range: –40°C to +85°C

• Packaging(Pb-free&GreenAvailable):
