When the serial clock input signal (CKIN leaps from low level to high level, the serial input data DIN is stored in register and the serial input changes to 3 bits parallel output; When the loading signal input (LIN leaps from low level to high level, the output of register is as the input of the output storage register. SC16722 applies for LED display device, and it can provide 3 driving output of heavy current. Also it adapts to various cascade applications.
