TB62701AN

16 Bit Constant Current LED Driver with Shift Register and Latch Functions

Product Description: The TB62701AN is specifically designed for LED display applications. The Bi-CMOS device has

16 Bi-polar constant current output channels and includes CMOS shift register and latch func-

tions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-50mA and is held constant across all 16 outputs effectively compensating for the inherent circuit and component variables which affect the bright- ness of the LEDs. Features:

• 16 Constant Current Output Channels
• Current Programmable from 5-50mA
• 5V CMOS Compatible Inputs
• Supports up to a 30V LED Supply Voltage Block Diagram: SDIP24-P-300 TB62701AN Weight: 1.2g(typ)
