Working Principles

The 74AHC74D-Q100J is a dual D-type flip-flop that operates on positive-edge-triggered clock signals. It stores data at the input (D) when a rising edge is detected at the clock (CLK) input. The stored data can be cleared or preset using the clear (CLR) and preset (PRE) inputs, respectively. The complementary outputs (Q̅ and Q) provide inverted and non-inverted versions of the stored data.

Detailed Application Field Plans

The 74AHC74D-Q100J is commonly used in various digital systems and applications, including:

1. Data storage and synchronization in microcontrollers and microprocessors.
2. State machine design in digital logic circuits.
3. Clock division and frequency multiplication circuits.
4. Serial-to-parallel and parallel-to-serial data conversion.
5. Control and sequencing circuits in communication systems.
6. Memory address decoding and control signal generation.
