Disadvantages: - Limited number of flip-flops in a single package (dual flip-flop). - Not suitable for applications requiring a large number of flip-flops.

Working Principles

The SN74AHC74NG4 is a dual D-type positive-edge-triggered flip-flop. It stores and transfers binary data based on the clock input signal. The flip-flop has two outputs, Q and Q̅, which represent the stored data and its complement, respectively. The asynchronous clear and preset inputs allow for resetting or setting the flip-flop to a specific state independent of the clock signal.

Detailed Application Field Plans

The SN74AHC74NG4 is commonly used in various digital systems and applications, including:

1. Data storage and transfer circuits
2. Sequential logic circuits
3. Microcontrollers and microprocessors
4. Communication systems
5. Control systems
6. Timing and synchronization circuits
