DESCRIPTION
The M74HC76 is an high speed CMOS DUAL J-K and PRESET (PR) are independent of the clock
FLIP FLOP WITH CLEAR fabricated with silicon and are accomplished by a logic low on the
gate C2MOS technology. corresponding input.
Depending on with the logic level at J and K All inputs are equipped with protection circuits
inputs, this device changes state on the negative against static discharge and transient excess
going transition of clock pulse (CK). CLEAR (CLR) voltage.
