Working Principles

The MC74HCT273ADWR2 operates based on the principles of D-type flip-flops. It stores and transfers data using positive-edge triggering. When the common clock input (CP) receives a rising edge, the data present at the D-inputs is transferred to the corresponding Q-outputs. The stored data remains unchanged until the next rising edge occurs.
