The CD74HCT109E operates based on the principles of J-K flip-flops. It consists of two independent flip-flops, each capable of storing one bit of information. The J and K inputs determine the behavior of the flip-flop, while the clock input synchronizes the internal operations.
When the clock signal transitions from low to high, the current state of the J and K inputs is captured and stored in the flip-flop. The outputs reflect the stored values until the next clock transition occurs. The set (MR) and reset (PR) inputs allow for asynchronous control of the flip-flop's state.
The CD74HCT109E is commonly used in various digital logic applications, including:
Its versatility and high-speed operation make it suitable for a wide range of applications where reliable digital signal processing is required.
