DESCRIPTION
The ULN2001A, ULN2002A, ULN2003 and
ULN 2004A are high voltage, high curren t darlington
arrays each containing seven open collector dar-
lington pairs with common emitters. Each channel
rated at 500m A and can wi thstand p eak c urre nts of
600mA. Suppression diodes are included for induc-
ti ve lo ad dr iv ing and the inputs are pin ned o pposi te
th e outputs t o s implify bo ar d lay out.
The four versions interface to all common logic fami-
lies :
ULN2001A General Purpose, DTL, TTL, PMOS,
CMOS
ULN2002A 14-25V PMOS
ULN2003A 5V T TL, CM OS
ULN2004A 6–15V CMOS, PMOS
These versatile devices are useful for driving a w ide
range of loads including solenoids, relays DC mo-
tors, LED displays filament lamps, thermal print-
heads a nd hi gh power buff er s .
The ULN2001A/2002A/2003A and 2004A are 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.
