MM74HCT74

Dual D-Type Flip-Flop with Preset and Clear

Features

General Description

■ Typical propagation delay: 20ns

The MM74HCT74 utilizes advanced silicon-gate CMOS

technology to achieve operation speeds similar to the

equivalent LS-TTL part. It possesses the high noise

immunity and low power consumption of standard

CMOS integrated circuits, along with the ability to drive

10 LS-TTL loads.

■

Low quiescent current: 40µA maximum (74HCT Series)

■ Low input current: 1µA maximum

■ Fanout of 10 LS-TTL loads

■ Meta-stable hardened

This flip-flop has independent data, preset, clear, and

clock inputs and Q and Q outputs. The logic level

present at the data input is transferred to the output

during the positive-going transition of the clock pulse.

Preset and clear are independent of the clock and

accomplished by a low level at the appropriate input.

The 74HCT logic family is functionally and pin-out

compatible with the standard 74LS logic family. All inputs

are protected from damage due to static discharge by

internal diode clamps to V and ground.

MM74HCT devices are intended to interface between

TTL and NMOS components and standard CMOS

devices. These parts are also plug-in replacements for

LS-TTL devices and can be used to reduce power

consumption in existing designs.
