SCT2168 8-bit Serial-In/Parallel-Out Constant Current Driver

The SCT2168 serial-interfaced LED driver sinks 8 LED clusters with constant current to keep the uniform intensity of LED displays. In applications, an external resistor is used to set the full-scale constant output current from 5mA up to 120mA. The SCT2168 guarantees each output can endure maximum 17V DC voltage stress. The built-in shift registers and data .
