DESCRIPTION

The ULN2001A, ULN2002A, ULN2003 and

ULN2004Aarehighvoltage,highcurrentdarlington

arrays each containing seven open collector dar-

lington pairs with common emitters. Each channel

rated at 500mAand can withstandpeak currentsof

600mA.Suppressiondiodesare includedfor induc-

tive load driving and the inputsare pinnedopposite

The ULN2001A/2002A/2003Aand 2004Aare sup-

plied in 16 pin plastic DIP packages with a copper

leadframe to reduce thermal resistance. They are

available also in small outline package (SO-16) as

ULN2001D/2002D/2003D/2004D.
