DESCRIPTION
The 74VCXH16245 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 2.3 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.
Bus hold on data inputs is provided in order to
eliminate the need for exte rnal pull-up or
pull-down resistor.
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.
