DESCRIPTION

The M74HC73 is an high speed CMOS DUAL J-K
FLIP FLOP WITH CLEAR fabrica ted with silicon
gate C

MOS 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.
