16-bit Serial-In/Parallel-Out Constant-Current LED Driver
Terminal Description
SCT2026
Pin Name
1 GND Ground terminal.
Function
2 SDI Serial input of data shift register.
3 CLK Clock input of shift register, data is sampled at the rising edge of CLK.
4
LA/
Input terminal of data strobe. Data is latched when LA/ is low. And data
on shift register goes through when LA/ is high.
5 -20 OUT[0:15] Open-drain, constant-current outputs.
21 OE/ Output enable signal. Output is enabled when OE/ is forced to low.
22 SDO Output terminal of serial-data output to the SDI of next SCT2026.
23 REXT Used to connect an external resistor for setting up all output current.
24 VDD Supply voltage terminal.
