DESCRIPTION

The VCXH162245 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. The device circuits

Ω

is including 26 series resistance in the A port

outputs. These resistors permit to reduce line

noise in high speed applications. Bus hold on

data inputs is provided in order to eliminate the

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.
