Working Principles

The CD74ACT109E operates based on the positive edge-triggered flip-flop principle. When the clock input (CP1 or CP2) receives a rising edge, the J-K data inputs (J1, K1, J2, K2) are sampled and transferred to the respective Q outputs (Q1, Q2). The clock enable inputs (CE1, CE2) control whether the clock signal is allowed to affect the flip-flop. The set and reset inputs (S, R, S̅, R̅) can be used to force the flip-flop into specific states.

Detailed Application Field Plans

The CD74ACT109E can be utilized in various digital logic applications, including but not limited to:

1. Synchronous Counters: The flip-flop's positive edge-triggering and clock enable inputs make it suitable for building synchronous counters, which are widely used in digital systems for counting and sequencing purposes.
2. Shift Registers: By connecting multiple CD74ACT109E flip-flops together, shift registers can be constructed. These are commonly employed for serial data storage and transfer applications.
3. General-Purpose Storage: The flip-flop's ability to store binary information makes it useful for general-purpose storage applications, such as register files or memory elements.
