M74HCT74 Dual D-Type Flip-Flop With Preset & Clear

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
