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)
