FUNCTION DESCRIPTION
SC16722 provides serial shift register and output storage register. 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.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
• Persons at a work bench should be earthed via a wrist strap.
• Equipment cases should be earthed.
• All tools used during assembly, including soldering tools and solder baths, must be earthed.
• MOS devices should be packed for dispatch in antistatic/conductive containers.
