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
2
C
MOS 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 transm ission is determined by DIR input.
The t wo enable inputs nG
canbeusedtodisable
the device so that the buses are effectively
isolated. The device circuits is including 26Ω series resistance in the A port outputs. These resistors permit to reduce line noise in high speed ap-

All inputs and outputs are equipped with
protection circuits against st atic discharge, giving
