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.

■ 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
