DESCRIPTION
The 74AC245 is an advanced high-speed CMOS
OCTAL BUS TRANSCEIVER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS tecnology.
This IC is intended for two-way asynchronous
communication between data buses and the
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..
All floating bus terminals during HIGH-Z state
must be held HIGH or LOW
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
