Working Principles

The MM74HCT74MX operates based on positive-edge triggering. When the CLK (Clock) input receives a rising edge, the data present at the D1 and D2 inputs are transferred to the Q1 and Q2 outputs, respectively. The CLR input can be used to clear the outputs, while the PRN/PRP inputs allow for presetting the outputs to desired states.
