HGSEMI ULN2803ADMTR Darlington array IC featuring eight NPN pairs for multi load driving applications

Product Overview

The ULN2803A is a high-voltage, high-current Darlington array integrated circuit, comprising eight NPN Darlington pairs. Designed for driving loads such as relays, DC lighting, stepper motors, and solenoid valves, it offers a wide operating voltage range and high output current capability (up to 500mA per channel). Each output features an open-collector design and a built-in clamp diode for inductive load suppression. The integrated 2.7K base resistors allow direct interface with TTL and 5V CMOS logic circuits, eliminating the need for standard logic buffers. This device is suitable for applications requiring multi-interface drive solutions due to its high operating voltage and current handling capabilities.
