DESCRIPTION
The 74VHC16245 is an advanced high-speed
CMOS 16-BIT BUS TRANSCEIVER (3-STATE)
fabricated
with
sub-micron
double-layer metal wiring C
2
MOS technology.
This IC is intended for two-way asynchronous
communication
between
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
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.
