Seven Darlington array
Datasheet − production data
Features
■Seven Darlingtons per package
■Output current 500 mA per driver (600 mA
peak)
■Output voltage 50 V
■Integrated suppression diodes for inductive
loads
■Outputs can be paralleled for higher current
■TTL/CMOS/PMOS/DTL compatible inputs
■Inputs pinned opposite outputs to simplify
layout
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 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, relays
DC motors, LED displays 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 ULN2001D1/2002D1/2003D1/
2004D1
