IDT74ALVCH32244

BUFFER/ DRIVER WITH

3-STATE OUTPUTS AND

BUS-HOLD

DESCRIPTION:

FEATURES:

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-

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

speedperformance.

• 0.5 MICRON CMOS Technology

• Typical tSK(o) (Output Skew) < 250ps

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

• VCC = 3.3V ± 0.3V, Normal Range

• VCC = 2.7V to 3.6V, Extended Range

• VCC = 2.5V ± 0.2V

• CMOS power levels (0.4µ W typ. static)

• Rail-to-Rail output swing for increased noise margin

• Available in 96-ball LFBGA package

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.

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for Heavy Loads

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
