DESCRIPTION
The 74LCXHR162245 is a low voltage CMOS 16
BIT BUS TRANSCEIVER (3-STATE) fabricated
with sub-micron silicon gate and double-layer
metal wiring C2MOS technology. It is ideal for low
power and high speed 3.3V applications; it can be
interfaced to 5V signal environment for both inputs
and outputs.
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data transmission is determined by DIR input.
The two enable inputs nG can beusedtodisable
the device so that the buses are effectively isolat-
ed.
Bus hold on data inputs is provided in order to
eliminate
the
need
for
external
pull-up
or
pull-down resistor.
All outputs, which are designed to sink up to
12mA, include 26
resistors to reduce overshoot
and undershoot.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
