The TB62715F/FN are specifically designed for LED display applications. The Bi-CMOS device has 8 Bipolar 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 2-150mA and is held constant across all 8 source outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs.
