Product Summary

The SD16730S is a special constant current driver for LED display application. The value of constant current can be determined with external resistor. The SD16730S bases on BICMOS technology and includes an 8-bit shift register. Latch and constant current driver. At the output stage, there are eight regulated current sources which provide 2-80mA constant current for driving LEDs by Bipolar Junction Transistor.
