PI74FCT3245

Fast CMOS 3.3V 8-Bit

Bidirectional Transceiver

Product Features

Product Description

Pericom Semiconductors PI74FCT3 series of logic circuits are

produced in the Companys advanced 0.6 micron CMOS

technology, achieving industry leading speed grades.

Advanced Low Power CMOS Operation

Compatible with LVC class of products

Compatible with industry standard

octal pinouts

Excellent output drive capability:

Balanced Drives (24 mA sink and source)

Can serve as a 5V to 3V translator

Inputs can be driven by 3.3V or 5V devices

Low ground bounce outputs

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)fromBportstoAports. Theoutputenable(OE)input, when

HIGH, disables both A and B ports by placing them in HIGH Z

condition.

Hysteresis on all inputs

Industrial operating temperature range:

-40 C to +85 C

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.
