Working Principles

The 74LVC273PW/AUJ operates based on the principles of D-type flip-flops. When a clock pulse is applied to the CP pin, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The clear input (CLR) can be used to reset all flip-flops simultaneously, setting their outputs to a known state. The output enable input (OE) controls whether the flip-flop outputs are active or in a high-impedance state.
