Additional Details

The DM5476J operates on a 5V power supply and has specific timing requirements for proper operation. The J and K inputs determine the next state of the flip-flop based on the clock signal. The master-slave configuration prevents the output from changing during the clock pulse, ensuring stable data transfer.
