Working Principles

The CD74AC273E is a positive-edge-triggered flip-flop that stores data based on the rising edge of the clock pulse. When the clock input (CP) receives a rising edge, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The asynchronous reset (active low) allows for clearing the flip-flop's contents when necessary.
