Working Principles

The MC74ACT74NG is a dual D-type flip-flop that operates on positive-edge-triggered clock signals. The flip-flop stores data at the D input when a rising edge is detected at the CLK input. The stored data is then available at the Q and Q̅ outputs. The CLR input asynchronously resets the flip-flop, forcing both outputs to a low state.

Detailed Application Field Plans

The MC74ACT74NG is widely used in digital systems where the storage and synchronization of data are required. Some common application fields include:

1. Microprocessors and microcontrollers
2. Communication systems
3. Data storage devices
4. Industrial automation
5. Consumer electronics
