Working Principles

The M74HC574B1R is a D-type flip-flop IC that operates based on clock pulses. When the clock pulse is applied, the input data is latched and stored in the flip-flops. The stored data is then transferred to the outputs upon receiving another clock pulse. The output enable pin allows the user to control the output stage, enabling or disabling data transfer as needed. The master reset pin resets all flip-flops to their initial state when activated.
