direction of data transmission is determined by

DIR input. The enable input G can be used to

disable the device so that the buses are effectively

isolated.

It has more speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All inputs are equipped with protection circuits

against static discharge, giving them 2KV ESD

immunity and transient excess voltage.

All floating bus terminals during High Z State must

be held HIGH or LOW.

DESCRIPTION

The 74LVC245A is a low voltage CMOS OCTAL

BUS TRANSCEIVER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS technology. It is ideal for 1.65 to 3.6

operations and low power and low noise

applications.

This IC is intended for two-way asynchronous

communication between data buses and the
