DESCRIPTION
The 74LVX16245 is an advanced high-speed
CMOS 16-BIT BUS TRANSCEIVER (3-STATE)
fabricated with sub-micron silicon gate and
double-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
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.
