DESCRIPTION

The M54HC73 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.
