Working Principles

The SN74LV74APWT is a dual D-type positive-edge-triggered flip-flop. It operates based on the principle of sequential logic, where binary data is stored and transferred. The flip-flop has two data inputs (D), which are synchronized with the clock input (CLK). On the rising edge of the clock signal, the data at the D input is transferred to the Q output, while the complement of the data is transferred to the Q̅ output. The state of the flip-flop can be cleared or preset using the CLR and PR inputs, respectively.
