Working Principles

The SN74AHCT74DE4 is a dual D-type positive-edge-triggered flip-flop. It stores and transfers data based on the rising edge of the clock signal. The data input (D) determines the state of the flip-flop, which is then latched and reflected at the outputs (Q and Q̅). The preset (PR) and clear (CLR) inputs allow for initialization and resetting of the flip-flop.
