DESCRIPTION
The ULN2001A, ULN2002A, ULN2003 and
ULN2004Aare high voltage,high current darlington
arrays each containing seven open collector darlington
pairs with common emitters. Each channel
rated at 500mAand can withstand peak currents of
600mA.Suppressiondiodesare included for inductive
load driving and the inputs are pinned opposite
the outputs to simplify board layout.
Thefour versionsinterfacetoallcommonlogicfamilies
:
ULN2001A General Purpose, DTL, TTL, PMOS,
CMOS
ULN2002A 14-25V PMOS
ULN2003A 5V TTL, CMOS
ULN2004A 6–15V CMOS, PMOS
Theseversatile devicesare useful for driving a wide
range of loads including solenoids, relays DC motors,
LED displays filament lamps, thermal printheadsand
high power buffers.
The ULN2001A/2002A/2003Aand 2004Aare 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.
