The ULN2001A, ULN2002A, ULN2003 and ULN2004Aare high voltage, high current darlington arrays each containing seven open collector darlingtonpairs with common emitters. Each channelis 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 four versions interfaceto all common logic families : ULN2001A
