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
