TB62708N

TOSHIBA Bi-CMOS Constant Current Interface Driver TB62708N 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.
