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.
Features:
• Current Source Device
• 16 Constant Current Output Channels
• Current Programmable from 5-90mA
• 5V CMOS Compatible Inputs
• 15MHz Max Clock Frequency (Cascade)
