74LS109 – Dual J-K Positive-edge-triggered Flip-Flops

74LS109 Dual J-K Positive-Edge-Triggered Flip-Flops IC

The 74LS109 is a high-performance integrated circuit featuring two independent J-K flip-flops. These flip-flops are positive-edge-triggered, ensuring reliable data capture on the rising edge of the clock pulse. Each flip-flop provides complementary outputs for versatile circuit design. Data on the J and K inputs can be changed while the clock is high or low, provided setup and hold times are met. This flexibility simplifies timing considerations in your projects. Additionally, dedicated preset and clear inputs allow for asynchronous control, setting or resetting outputs independently. Ideal for a wide range of sequential logic applications, the 74LS109 offers robust and predictable operation. It's a fundamental component for building counters, registers, and control circuits.
