SCT2110 8-bit Serial-In/Parallel In-Out Constant-Current LED Driver

The SCT2110 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 160mA. The SCT2110 guarantees each output can endure maximum 17V DC voltage stress. The built-in shift registers and data.
