8-bit Serial-In/Parallel-Out Constant-Current LED Driver Product Description
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 latches making the SCT2110 effective solution in driving LED display. The output enable function gates all 8 outputs on and off, and is fast enough to be used as PWM input for LED intensity control. Since the serial data input rate can be reached up to 25MHz, the SCT2110 will satisfy system which needs high volume data transmission to control the LED display.
