Working Principles

The MC74ACT74DR2G is a dual D-type positive-edge-triggered flip-flop. It operates based on the rising edge of the clock pulse (CP) input. The data input (D) is sampled and stored when the clock signal transitions from LOW to HIGH. The complementary outputs (Q and Q̅) provide inverted and non-inverted versions of the stored data. The asynchronous clear input (CLR) allows for resetting the flip-flop to a known state.

Detailed Application Field Plans

The MC74ACT74DR2G can be used in various digital systems and applications, including: 1. Data storage and transfer circuits 2. Synchronous and asynchronous counters 3. State machines and sequential logic circuits 4. Clock synchronization and distribution circuits 5. Control and timing circuits in microprocessors and microcontrollers
