ULN2803ADWR is a high voltage and high current darlington transistor array. It consist of 8 NPN darlington pairs. Each darlington pairs features 500mA rated collector current, and 50V voltage outputs with common-cathode clamp diodes for switching inductive loads. The inputs compatible with various types of logic.

The applications of ULN2803A are typically for usage on driving a high voltage and/or current peripheral from an MCU or logic device that cannot tolerate these conditions.
