Working Principles

DM74LS574N functions as a flip-flop, which means it can store and transfer data based on the clock signal. When the clock signal transitions from low to high (rising edge), the data present at the inputs (D0-D7) is latched and stored in the corresponding output registers (Q0-Q7). The stored data remains unchanged until the next rising edge of the clock signal.
