The ULN2003 is a high-voltage, high-current Darlington array with seven open collector Darlington pairs and common emitters. Each channel is rated at 500 mA and has a peak current rating of 600 mA. For inductive load driving, suppression diodes are added, and the inputs are pinned opposite the outputs to simplify board layout. These adaptable devices can supply a variety of loads, including solenoids, relay DC motors, LED display filament lights, thermal printheads, and high-power buffers. To decrease heat resistance, the ULN2003 is packaged in a 16-pin DIP package with a copper lead frame.
