DESCRIPTION

The 74VCX162245 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 beusedtodisable

the device so that the buses are effectively

isolated. The device circuits is including 26

Ω se-

ries resistance in the A port outputs. These resis-

tors permit to reduce line noise in high speed ap-
