The ULN2803 is a high-voltage, high-current Darlington transistor array featuring eight open-collector common-emitter pairs, each rated at 500mA. Designed for driving a wide range of inductive loads, it includes output clamp diodes and inputs compatible with various logic types. Its pinout opposition simplifies board layout, making it suitable for applications such as relay drivers, solenoids, DC motors, LED displays, filament lamps, thermal print-heads, and high-power buffers. Available in SOP18 and QFN20(4x4) packages.
