Dual D-Type Flip-Flop with

Preset and Clear

SOIC−14 NB

CASE 751A−03

MM74HCT74

General Description

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.

TSSOP−14 WB

CASE 948G

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.

MARKING DIAGRAM

HCT74A

AWLYWW

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 VCC and

ground.

SOIC−14 NB

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.
