TB62707F

8 Bit Constant Current LED Driver with Latch Function

Product Description:

The TB62707F is specifically designed for LED display applications. The Bi-CMOS device has 8
Bi-polar constant current output channels and includes CMOS latch function.

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 8 outputs effectively
compensating for the inherent circuit and
component variables which affect the brightness
of the LEDs.

Features:

· 8 Constant Current Output Channels
· Current Programmable from 5-90mA
· 5V CMOS Compatible Inputs
· Surface Mount Package
