DESCRIPTION
The ULN2001A, ULN2002A, ULN2003 and
ULN2004A are high voltage, high current darlington
arrays each containing seven open collector darlington pairs with common emitters. Each channel
rated at 500mA and can withstand peak currents of
600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite
theoutputs to simplify board layout.
The four versions interface to all common logic families :

ULN2002A

ORDERING NUMBERS: ULN2001D/2D/3D/4D

6–15V CMOS, PMOS

These versatile devices are useful for driving a wide
range of loads including solenoids, relays DC motors, LEDdisplays filament lamps, thermal printheads and high power buffers.
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.
