Working Principles

The SN74LVC574ADWR operates as an octal D-type flip-flop with 3-state outputs. It stores and transfers data based on clock pulses received at the CP input. The data inputs (D0-D7) are latched and stored when a rising edge is detected at the CP input. The stored data can be accessed through the corresponding output pins (Q0-Q7). The output enable (OE) input controls the output state, allowing the outputs to be either active or in a high-impedance state.
