SCT2110 V03_01; Mar/08
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.
