Working Principles

The 74LVQ74SJX is a dual D-type positive-edge-triggered flip-flop. It operates by capturing the input data (D) at the rising edge of the clock signal (CLK). The captured data is then stored in the flip-flop's internal memory and made available at the output pins (Q and Q̅). The clear (CLR) and preset (PRE) inputs allow for resetting or setting the flip-flop to specific states as required.
