The
ULN2001A, ULN2002A, ULN2003 and
ULN2004A are high voltage, high current darlington
arrays each containing seven open collector darlington pairs 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.
