DESCRIPTION:

FEATURES:

–

0.5 MICRON CMOS Technology

The LVCH374A octal edge triggered D-Type flip-flop is built using

advanced dual metal CMOS technology. The device features 3-state

outputsdesignedspecificallyfordrivinghighlycapacitiveorrelativelylow-

impedanceloads.TheLVCH374Aisparticularlysuitableforimplementing

buffer registers, input-output (I/O) ports, bidirectional bus drivers, and

working registers.

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

> 200V using machine model (C = 200pF, R = 0)

All inputs, outputs and I/O are 5 Volt tolerant

Supports hot insertion

A buffered output-enable (OE) input can be used to place the eight

outputs in either a normal logic state (high or low logic levels) or a high-

Drive Features for LVCH374A:

–

High Output Drivers: ±24mA

Reduced system switching noise

APPLICATIONS:

The LVCH374A has been designed with a ±24mA output driver. This

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

speedperformance.

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems

the use of this device as a translator in a mixed 3.3V/5V system environ-

ment.

The LVCH374A has “bus-hold” which retains the inputs’ last state
