Working Principles

The SN74LVC74APWG4 operates as a dual D-type positive-edge-triggered flip-flop. It can store and manipulate digital data based on the input signals received. The CLK (clock) input triggers the flip-flop to capture the data present at the D (data) input. The stored data is then available at the Q and Q̅ outputs.

The flip-flop also features asynchronous reset (CLR) and preset (PRE) inputs, allowing for additional control over the stored data. When the CLR input is activated, the flip-flop is reset to a known state. Conversely, the PRE input sets the flip-flop to a predefined state.
