Working Principles

The MM74C74MX operates based on the principles of sequential logic. When the clock input (CLK) receives a rising edge, the data input (D) is transferred to the output (Q) and its complement (Q̅). The stored information remains unchanged until the next clock pulse triggers a new data transfer. The clear input (CLR) synchronously resets both flip-flops when activated.
