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 C
2
MOS 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
canbeusedto
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.
