The ULN2001, ULN2002, ULN2003 and ULN2004 are high voltage, high current darlington arrays each containing seven open collector darlington pairs with common emitters. Each channel rated at 500mA and can withstand peak currents of 600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
The ULN200XA/XD1 is a seven‑channel darlington array designed for driving loads such as solenoids, relays, DC motors, LED displays, filament lamps, and thermal printheads. It offers 500 mA continuous collector current per driver and includes integrated suppression diodes for inductive loads.
