74LS109 Dual J-K Positive Edge-Triggered Flip-Flop IC The 74LS109 Dual J-K Positive Edge-Triggered Flip-Flop IC, also referred to as the 74109 IC, features two independent flip-flops designed for positive-edge clock triggering. Each flip-flop includes asynchronous preset and clear inputs that can override all other signals, ensuring reliable reset or set operations. This JK flip-flop IC allows flexibility in design—it can function as a toggle flip-flop by grounding the K input and tying J high, or as a D-type flip-flop by connecting both J and K inputs. The 74109 IC is ideal for timing, data storage, and sequential logic applications, supporting a temperature range of 0°C to 70°C. With a variety of packaging options, including plastic and ceramic DIPs, this IC is a trusted choice for TTL-based digital systems. Features: Dual J-K positive-edge-triggered flip-flops Asynchronous preset and clear inputs Edge-triggered clock input for precise timing Operates as JK or D-type flip-flop TTL compatible logic levels Low power consumption Noise-immune circuitry
