Working Principles

The 74AHCT74PW,112 is a dual D-type flip-flop that stores binary data using positive-edge-triggered clock signals. When the clock input (CLK) transitions from low to high, the data input (D) is captured and stored in the flip-flop. The stored data can be accessed through the complementary outputs (Q and /Q). The flip-flop can be cleared or set using the respective inputs (CLR and SET), allowing for controlled data manipulation.
