DESCRIPTION

The 74AC16245 is an advanced high-speed

CMOS 16-BIT BUS TRANSCEIVER (3-STATE)

fabricated with sub-micron silicon gate and dou-

ble-layer metal wiring C2MOS technology.

This IC is intended for two-way asynchronous

communication between data busses; the

direction of data transmission is determined by

DIR input. The enable input G can be used to

disable the device so that the busses are

effectively isolated.

All inputs and outputs are equipped with protec-

tion 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.
