Working Principles

The SN74HC74NSRE4 is a dual D-type flip-flop that operates on positive-edge triggering. It stores data at the inputs (D1 and D2) when a rising edge is detected at the clock input (CLK). The stored data can be cleared or preset using the clear (CLR) and preset (PRE) inputs, respectively. The complementary outputs (Q1', Q2') provide the logical complement of the main outputs (Q1, Q2). The output enable (OE) input controls the output state.

Detailed Application Field Plans

The SN74HC74NSRE4 is commonly used in various digital circuit applications, including:

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