General Description

The ULN2803 is high-voltage high-current Darlington transistor arrays each containing eight open

collector common emitter pairs. Each pair is rated at 500mA. Suppression diodes are included for

inductive load driving, the inputs and outputs are pinned in opposition to simplify board layout.

These devices are capable of driving a wide range of loads including solenoids, relays, DC motors, LED

displays, filament lamps, thermal print-heads and high-power buffers.

The ULN2803 is available in SOP18 and QFN20(4x4) packages.
