DESCRIPTION

The M74HCT74 is an high speed CMOS DUAL D

TYPE FLIP FLOP WITH CLEAR fabricated with

silicon gate C2MOS technology.

A signal on the D INPUT (nD) is transferred on the

Q OUTPUT during the positive going transition of

the clock pulse. CLEAR (CLR) and PRESET (PR)

are independent of the clock and accomplished by

a low on the appropriate input.

The M74HCT74 is designed to directly interface

HSC2MOS

systems

with

TTL

and

NMOS

components.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
