DESCRIPTION
The ULN2001A, ULN2002A, ULN2003 and
ULN200 4A are high volta ge, high cu rrent da rlington
arrays each containing seven open collector darlington pairs with common emitters. Each channel
rated at 500m A and can wi thstand p eak c urre nts of
600mA. Sup pression dio des are inc luded for indu ctive lo ad dr iv ing and the in put s a re pinned oppo si te
the outputs t o s im pli fy board layout.
The four vers ions interface to all com mon logic families :
ULN2001A General Purpose, DTL, TTL, PMOS,
CMOS
ULN2002A 14-25V PMOS
ULN2003A 5V TTL, CMOS
ULN2004A 6–15V CMOS, PMOS
These versatile d evices are usef ul for driv ing a wide
range of loads including solenoids, relays DC motors, LED displays filament lamps, thermal printheads and high power buffer s .
The ULN2001A/2002A/2003A and 2004A are supplied 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.
