DESCRIPTION

The 74VCX16245 is a low voltage CMOS 16 BIT
BUS TRANSCEIVER (3-STATE) fabricated with
sub-micron silicon gate and five-layer metal wiring
C

2

MOS technology. It is ideal f or low power and
very high speed 1.8 to 3.6V applications; it can be
interfaced to 3.6V signal environment for both
inputs and outputs.
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data transm ission is determined by DIR input.
The t wo enable inputs nG

canbeusedtodisable
the device so that the buses are effectively
isolated.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
All floating bus terminals during High Z State must
be held HIGH or LOW.
