The ULN2001, ULN2002, ULN2003 and ULN2004 are high voltage, high current Darlingtonarrays each containing seven open collectorDarlington pairs with common emitters. Eachchannel rated at 500 mA and can withstand peakcurrents of 600 mA. Suppression diodes areincluded for inductive load driving and the inputsare pinned opposite the outputs to simplify boardlayout.
