DM115B

8-Bit CONSTANT CURRENT LED DRIVERS with

3.3v ~ 5v Supply Voltage

General Description

The DM115B is the constant current driver specifically designed for LED display applications.

The value of constant current can be varied using an external resistor. The devices include an 8-bit

shift register, latches, and constant current drivers on a single Silicon CMOS chip.
