DESCRIPTION

The 74LCXH16245 is a low voltage CMOS 16 BIT

BUS TRANSCEIVER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS 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.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power con-

sumption.

All inputs and outputs are equipped with protec-

tion 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.
