M74HC109 is a 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.
The M74HC109 is a high-speed CMOS dual J-K flip-flop with preset and clear, fabricated with silicon gate CMOS technology. It is pin and function compatible with the 74 series 109 and features balanced propagation delays and symmetrical output impedance. The device operates with a wide voltage range from 2V to 6V and includes protection circuits against static discharge and transient excess voltage.
