Working Principles

The MC74HCT273ADWR2G operates based on the principles of D-type flip-flops. It stores and transfers data based on clock pulses received at the CP input. When a clock pulse is detected, the data inputs (D0-D7) are latched and stored in their respective flip-flops. The stored data can then be accessed from the output pins (Q0-Q7). The master reset input (MR) allows for clearing all flip-flops simultaneously.
