IDT74ALVCH32245

3.3V CMOS 32-BIT

BUS TRANSCEIVER

WITH 3-STATE OUTPUTS

AND BUS-HOLD

DESCRIPTION:

This 32-bit bus transceiver is built using advanced dual metal CMOS

technology. This high-speed, low power transceiver is ideal for asynchro-

nous communication between two busses (A and B). The Direction and

Output Enable controls are designed to operate the device as either four

independent 8-bit transceivers or one 32-bit transceiver. The direction

control pins (DIR) control the direction of data flow. The output enable pins

(OE) override the direction control and disable both ports. All inputs are

designed with hysteresis for improved noise margin.

The ALVCH32245 has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speed performance.

The ALVCH32245 has “bus-hold” which retains the inputs’ last state

whenever the input bus goes to a high impedance. This prevents floating

inputs and eliminates the need for pull-up/down resistors.
