Working Principles

SN74HCT74PW consists of two independent D-type flip-flops with asynchronous clear and preset inputs. The flip-flops are triggered by the rising edge of the clock signal, allowing synchronized operation. The data input (D) determines the state of the flip-flop, which is then stored until the next clock pulse. The clear and preset inputs allow for resetting the flip-flop to a known state.
