Description

The 54VCXH162245 is a low voltage CMOS 16

bit bus transceiver (3-state) fabricated with sub-

micron silicon gate and five-layer metal wiring

very high speed 1.65 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. The device circuits is including 26Ω

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. All floating bus terminals during High Z

State must be held HIGH or LOW.

MOS technology. It is ideal for low power and
