Working Principles

The SN74ALS874BDWRE4 operates based on the principles of D-type flip-flops. The data inputs (D0-D7) store the input values when a clock pulse is applied to the CP pin. The stored values are then available at the corresponding flip-flop outputs (Q0-Q7). The clear input (CLR) can be used to reset all flip-flops to a known state. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.
