DESCRIPTION
SD16730 is a special constant current driver for LED display application. The value of constant current can be determined with external resistor. It 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.

FEATURES
* Output current adjustable through an external resistor
* Serial data in/out
* 8 constant-current output channels
* Output current: 2-80mA
* 20MHz clock frequency
* Current accuracy (All output ON)

APPLICATIONS
* LED guardrail diode
