Working Principles

The CD74AC374M operates based on the principles of D-type flip-flops. It stores and transfers data using clock signals. When the clock input (CP) transitions from low to high, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data is then available at the corresponding output pins (Q0-Q7). The output enable input (OE) controls whether the outputs are active or in a high-impedance state.
