Working Principles

The 74LVQ74SJ is a sequential logic device that consists of two D-type flip-flops. It operates on positive clock edges and stores data based on the input at the D pin. The stored data is then available at the Q and /Q outputs. The clear (CLR) and preset (PRE) inputs allow for resetting or setting the flip-flop outputs to specific states. The IC operates within a specified supply voltage range and provides non-inverting outputs.
