Working Principles

The SN74LVC74AQDRQ1 is a dual D-type flip-flop that stores and transfers data based on the clock signal. The flip-flop operates on the rising edge of the clock signal, capturing the data input and storing it in its internal memory. The stored data is then available at the complementary output pins. The clear and preset inputs allow for synchronous clearing and setting of the flip-flop's state.
