DESCRIPTION

The 74VCXR162245 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 and B port outputs. These

resistors permit to reduce line noise in high speed

applications.

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.
