DESCRIPTION
Serial-data output: SER OUT is the serial data output of the 12−bit serial shift register. The
purpose of this pin is to cascade several devices on the serial bus. By connecting the SER
O
OUT pin to the SER IN input of the next device on the serial bus to cascade, the data
transfers to the next device on the falling edge of SRCK. This can improve the cascade
application reliability, as it can avoid the issue that the second device receives SRCK and
data input at the same rising edge of SRCK.
I
Shift-register clock: SRCK is the serial clock input. On each rising SRCK edge, data
transfers from SER IN to the internal serial shift registers.
I
Power supply: V_CC is the power supply pin voltage for the device. TI recommends adding a
0.1 μF ceramic capacitor close to the pin.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
