Working Principles

The MC74HC273ADTR2 operates based on the principles of D-type flip-flops. Each flip-flop stores a single bit of data, which can be either a logic HIGH or LOW level. The clock pulse input (CP) controls the transfer of data from the data inputs (D0-D7) to the outputs (Q0-Q7). When a clock pulse is applied, the data present at the inputs is transferred to the corresponding outputs. The master reset input (MR) allows for the simultaneous clearing of all flip-flops when activated.
