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

C2MOS technology. It is ideal for 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 transmission is determined by DIR input.

The two enable inputs nG can be used to disable

the device so that the buses are effectively

isolated.

All inputs and outputs are equipped with

protection 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.
