DESCRIPTION The M74HC73 is an high speed CMOS DUAL J-K FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology. Depending on the logic level applied to J and K inputs, this device changes state on the negative going transition of clock input pulse (CK). The
clear function is accomplished independently of the clock condition when the clear input (CLR) is taken low. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
