Working Principles

The SN74AHCT74MPWREP is a dual D-type positive-edge-triggered flip-flop. It operates based on the rising edge of the clock signal (CLK). When the CLK input transitions from LOW to HIGH, the data present at the D input is transferred to the Q and Q̅ outputs. The complementary outputs provide both inverted and non-inverted versions of the input data.

The flip-flop can be cleared using the CLR input, which is active LOW. When CLR is brought LOW, both Q and Q̅ outputs are forced to logic LOW state. Similarly, the PR input (active LOW) can be used to preset the flip-flop outputs to logic HIGH state.
