16 Bit Constant Current LED Source Driver with Shift Register and Latch Functions

Product Description: The TB62708N is specifically designed for LED display applications. The Bi-CMOS device has

16 Bi-polar constant current output source channels and includes CMOS shift register and latch

functions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-90mA and is held constant across all 16 source outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs. Features:

Current Source Device
16 Constant Current Output Channels
Current Programmable from 5-90mA
5V CMOS Compatible Inputs
