Working Principles

SN74LVC74ADE4 operates based on positive-edge-triggered D-type flip-flop logic. When the clock input (CLK1 or CLK2) transitions from low to high, the data input (D1 or D2) is captured and stored in the corresponding flip-flop. The stored data is then available at the respective output (Q1 or Q2). The clear input (CLR or CLR') can be used to reset the flip-flops to a known state, while the preset input (PR) can set the flip-flops to a desired state.
