Working Principles

The 74LVC821APW,112 operates based on the principles of D-type flip-flops. It stores and transfers data using clock pulses. When the clock pulse input (CP) transitions from low to high, the data present at the data inputs (D0-D7) is transferred to the corresponding output pins (Q0-Q7). The output enable (OE) pin controls the state of the outputs. When OE is low, the outputs are enabled and reflect the stored data. When OE is high, the outputs are in a high-impedance state.
