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.
