DESCRIPTION

The VCXH16245 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 2.3 to 3.6V applications; it can

be interfaced to 3.6V signal enviroment for both

inputs and outputs.

This IC is intended for two-way asynchronous

communication beetwen data buses; the direction

of data trasmission is determined by DIR input.

The two enable inputs nG can be used to disable

the device so that the buses are effectively

isolated. Bus hold on data inputs is provided in

order to eliminate te need for external pull-up or

pull-down resistor.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
