Description
The ULN2001, ULN2002, ULN2003 and ULN
2004 are high-voltage, high-current Darlington
arrays each containing seven open collector
Darlington pairs with common emitters. Each
channel is rated at 500 mA and can withstand
peak currents of 600 mA. Suppression diodes are
included for inductive load driving and the inputs
are pinned opposite the outputs to simplify board
layout.
The versions interface to all common logic
families: ULN2001 (general purpose, DTL, TTL,
PMOS, CMOS); ULN2002 (14 – 25 V PMOS);
ULN2003 (5 V TTL, CMOS); ULN2004 (6 – 15 V
CMOS, PMOS).
These versatile devices are useful for driving a
wide range of loads including solenoids, relay DC
motors, LED display filament lamps, thermal
printheads and high-power buffers.
The ULN2001A/2002A/2003A and 2004A are
supplied in a 16-pin DIP package with a copper
leadframe to reduce thermal resistance. They are
available also in small outline package (SO-16) as
ULN2001D1/2002D1/2003D1/ 2004D1.
ULN2003 is also available in TSSOP16 package,
for reduced application space.
