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.
LOGIC DIAGRAM
This IC is intended for two-ways asynchronous
communication between data buses: the direction
of data trasmission is determined by DIR input.
Any nG contol output governs eight BUS
TRANSCEIVERS. Output Enable input (nG) tied
together gives full 32-bit operation. When nG is
LOW, the output are enabled. 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.
