8 Bit Constant Current LED Source Driver with

Shift Register and Latch Functions

TB62715F/FN

Product Description:

The TB62715F/FN are specifically designed for LED

display applications. The Bi-CMOS device has 8 Bi-

polar constant current output source channels and

includes CMOS shift register and latch functions.

The LED drive current is programmed by the installa-

tion of a single resistor per device. Current is pro-

grammable 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.
