Working Principles

The MC74LCX74DG is a dual D-type positive edge-triggered flip-flop. It operates based on the positive edge of the clock signal. The data input (D) is transferred to the Q and Q̅ outputs when the clock signal transitions from low to high. The set (SET) and clear (CLR) inputs allow for asynchronous control of the flip-flop's state.
