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.
■ HIGH SPEED : fMAX= 67MHz (TYP.) at VCC= 6V
■ LOW POWER DISSIPATION: ICC=2µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH= VNIL= 28 % VCC(MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL= 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 74
