DESCRIPTION The M74HC74 is an high speed CMOS DUAL D TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology. A signal on the D INPUT is transferred on the Q OUTPUT during the positive going transition of the clock pulse. CLEAR and PRESET are
independent of the clock and accomplished by a low on the appropriate input. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
