3.3V CMOS

IDT74ALVCH244

OCTAL BUFFER/DRIVER

WITH 3-STATE OUTPUTS

AND BUS-HOLD

DESCRIPTION:

FEATURES:

–

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

The ALVCH244 octal buffer/driver is built using advanced dual metal

CMOS technology. The ALVCH244 is organized as two 4-bit line drivers

withseperateoutput-enable(OE)inputs.WhenOEislow,thedevicepasses

datafromtheAinputs totheYoutputs.WhenOEis high,theoutputs arein

thehigh-impedancestate.

–

= 2.7V to 3.6V, Extended Range

To ensure the high-impedance state during power up or power down,

OE shouldbe tiedtoVCC througha pullupresistor;the minimumvalue of

the resistoris determinedbythe current-sinkingcapabilityofthe driver.

VCC = 2.5V ±0.2V

CMOS power levels (0.4µW typ. static)

Rail-to-Rail output swing for increased noise margin

Available in SOIC, SSOP, QSOP, and TSSOP packages

The ALVCH244 has been designed with a ±24mA output driver. This

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

speedperformance.

Drive Features for ALVCH244:

–

High Output Drivers: ±24mA

Suitable for heavy loads

The ALVCH244 has a “bus-hold” which retains the inputs’ last state

wheneverthe inputbus goes toa highimpedance.This prevents floating

inputs andeliminates the needforpull-up/downresistors.

APPLICATIONS:

• 3.3V High Speed Systems

• 3.3Vandlowervoltagecomputingsystems
