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 be used to disable

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 26Ω 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.
