The ULN2004 is a high voltage, high current Darlington array each containing seven open collectors Darlington pairs with common emitters. Each channel is 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 ULN2004 is supplied in 16 pin plastic DIP packages with a copper lead frame to reduce thermal resistance. It is available also in a small outline package (SO-16).
