DESCRIPTION
The M74HC76 is an high speed CMOS DUAL J-K
FLIP FLOP WITH CLEAR fabricated with silicon
gate C2MOS technology.
Depending on with the logic level at J and K
inputs, this device changes state on the negative
going transition of clock pulse (CK). CLEAR (CLR)

and PRESET (PR) are independent of the clock
and are accomplished by a logic low on the
corresponding input.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + I CC/2 (per FLIP/
FLOP)
