The SN74HC109NSR is a dual J-K positive-edge-triggered flip-flop designed by Texas Instruments. It operates within a voltage range of 2 V to 6 V and features low input current of 1 OºA maximum, making it suitable for low-power applications with a maximum supply current of 40 OºA. The device can drive up to 10 LSTTL loads with ¬±4 mA output drive at 5 V. This flip-flop includes preset (PRE) and clear (CLR) inputs that allow for setting or resetting the outputs independently of other inputs. Data at the J and K inputs is transferred to the outputs on the positive edge of the clock pulse, provided the setup-time requirements are met. The typical propagation delay (t_pd) is 12 ns, which supports efficient timing operations. The SN74HC109NSR is available in a 16-pin SOP package and operates within a temperature range of -40¬8C to 85¬8C, making it suitable for a variety of applications.
