DESCRIPTION
The 74VHC16245is an advanced high-speed
CMOS 16-BIT BUS TRANSCEIVER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiringC2 MOS technology.
This ICis intended for two-way asynchronous
communication between data busses; the
directionof data transmissionis determined by
DIR input. The enable inputG canbe usedto
disable the device so that the busses are
effectively isolated.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
All floating bus terminals during HighZ State must held HIGHor LOW.
