DESCRIPTION

The 74ALVCH32245 is a low voltage CMOS
32-BIT BUS TRANSCEIVER (3-STATE)
fabricated with sub-micron silicon gate and
five-layer metal wiring C

2

MOS technology. It is
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-ways asynchronous
communication between data buses: the direction
of data trasmission is determined by DIR input.
Any nG
TRANSCEIVE RS. Output Enable input (nG
together gives full 32-bit operation. When nG
LOW, the output are en abled. W hen nG

contol output governs eight BUS

) tied

is

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 stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
