Working Principles

The 74LVTH574D,112 is a positive-edge-triggered flip-flop. It stores and transfers data based on the clock pulse input (CP). When the CP signal transitions from low to high, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data can then be accessed through the corresponding flip-flop outputs (Q0-Q6). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.
