IDT74ALVCH32244

3.3V CMOS 32-BIT

BUFFER/ DRIVER WITH

3-STATE OUTPUTS AND

BUS-HOLD

DESCRIPTION:

This 32-bit buffer/driver is built using advanced dual metal CMOS

technology. This high-speed, low power device offers bus/backplane

interface capability with improved packing density. The device has a flow-

through organization for simplifying board layout. The three-state controls

operate this device in a Quad-Nibble, Dual-Byte or single 16-bit word mode.

All inputs are designed with hysteresis for improved noise margin.

The ALVCH32244 has been designed with a ±24mA output driver. This

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

speed performance.

The ALVCH32244 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.

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
