DESCRIPTION

The 74VCXH32245 is a low voltage CMOS QUAD

32-BIT

BUS

TRANSCEIVER

(3-STATE)

fabricated

with

sub-micron silicon gate and

ideal for 1.65 to 3.6 V applications; it can be

interfaced to 3.6V signal enviroment for both

inputs and outputs.

This IC is intended for two-way asynchronous

communication between data buses: the direction

of data trasmission is determined by DIR input.

Any

nG

contol

output

governs

four

BUS

TRANSCEIVER. Output Enable input (nG) tied

together gives full 32-bit operation. When nG is

LOW, the output are on. When nG is HIGH, the

output are in high impedance state so that the

buses are effectively isolated. 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.
