M74HC109 Dual J-K Flip-Flop With Preset & Clear

The M74HC109 is an high speed CMOS DUAL J-K FLIP FLOP WITH PRESET AND CLEAR fabricated with silicon gate C2MOS technology. In accordance with the logic level on the J and K input this device changes state on positive going transition of the clock pulse. CLEAR and PRESET are independent of the clock and are accomplished by a logic low on the corresponding input.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.
