Working Principles

The 74HC74D-Q100HL is a dual D-type flip-flop that operates based on clock pulses. The D input determines the state of the flip-flop, which is latched and stored when a clock pulse is applied. The clear input allows for synchronous reset of the flip-flops, setting the outputs to a known state. The complementary outputs provide both the normal and inverted versions of the stored data.

Detailed Application Field Plans

The 74HC74D-Q100HL can be used in various digital logic applications, including but not limited to:

1. Sequential logic circuits
2. Data storage and transfer systems
3. Counters and frequency dividers
4. State machines and control units
5. Clock synchronization circuits
