Working Principles

The MM74HC74ASJX is a dual D-type positive edge-triggered flip-flop. It operates by storing and transferring data based on the clock signal. The flip-flop has two inputs, D1 and D2, which are used to input data. On the rising edge of the clock signal, the data from the inputs is transferred to the respective outputs, Q1 and Q2. The clear input (CLR) can be used to reset the outputs to a known state.
