DESCRIPTION

The

ULN2001A,

ULN2002A,

ULN2003

and

ULN2004A are high voltage, high current darlington

arrays each containing seven open collector dar-

lington pairs with common emitters. Each channel

rated at 500mA and can withstand peak currents of

600mA. Suppression diodes are included for induc-

tive load driving and the inputs are pinned opposite

the outputs to simplify board layout.

The four versions interface to all common logic fami-

lies :

ULN2001A

General Purpose, DTL, TTL, PMOS,

CMOS

ULN2002A

14-25V PMOS

ULN2003A

5V TTL, CMOS

ULN2004A

6–15V CMOS, PMOS

These versatile devices are useful for driving a wide

range of loads including solenoids, relays DC mo-

tors, LED displays filament lamps, thermal print-

heads and high power buffers.

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.
