DESCRIPTION  
The M74HC76 is an high speed CMOS DUAL J-K  
FLIP FLOP WITH CLEAR fabricated with silicon  
gate C MOS technology.  
and PRESET (PR) are independent of the clock  
and are accomplished by a logic low on the  
corresponding input.  
2
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)  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.
