SD16730
8-Bit Constant Current LED Driver
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.
