Working Principles

The CD74ACT109ME4 is a dual J-K positive-edge-triggered flip-flop. It operates based on the clock input (CLK) and the J-K data inputs (J1, K1, J2, K2). On each rising edge of the clock signal, the flip-flops latch the data present at the J and K inputs. The outputs (Q1, Q1̅, Q2, Q2̅) reflect the latched data after a small propagation delay.

The clear input (CLR) and preset input (PRE) allow for resetting or setting the flip-flop outputs to specific states. When the clear input is activated (low), both flip-flop outputs are forced to logic low. Conversely, when the preset input is activated (low), both outputs are set to logic high.

Detailed Application Field Plans

The CD74ACT109ME4 can be used in various digital applications, including but not limited to: - Sequential logic circuits - Counters and dividers - State machines and control units - Data storage and retrieval systems - Synchronous communication interfaces
