TRANSPARENT D-TYPE

LATCH 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

This octal transparent D-type latch is built using advanced dual metal

CMOS technology. The ALVCH373 device is particularly suitable for

implementing buffer registers, I/O ports, bidirectional bus drivers, and

workingregisters.While the latch-enable (LE)inputis high,the Qoutputs

followthe data (D)inputs.WhenLEis takenlow,the Qoutputs are latched

atthe logiclevels setupatthe Dinputs.

Drive Features for ALVCH373:

–

High Output Drivers: ±24mA

Suitable for heavy loads

The ALVCH373 has been designed with a ±24mA output driver. This

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

speedperformance.

APPLICATIONS:

The ALVCH373 has a “bus-hold” which retains the inputs’ last state

wheneverthe inputbus goes toa highimpedance.This prevents floating

inputs andeliminates the needforpull-up/downresistors.
