DARLINGTON TRANSISTOR ARRAYS
Description
The ULN2002A, ULN2003A and ULN2004A are high voltage, high
current Darlington arrays each containing seven open collector
common emitter pairs. Each pair is rated at 500mA. Suppression
diodes are included for inductive load driving, the inputs and outputs
are pinned in opposition to simplify board layout.
Pin Assignments
Device options are designed to be compatible with common logic
families:
ULN2002A (14-25V PMOS)
ULN2003A (5V TTL, CMOS)
ULN2004A (6-15V CMOS, PMOS)
These devices are capable of driving a wide range of loads including
solenoids, relays, DC motors, LED displays, filament lamps, thermal
print-heads and high-power buffers.
The ULN2002A, 2003A and 2004A are available in both a small
outline 16-pin package (SO-16) and DIP-16 package.
SO-16/DIP-16
Features

High Voltage Outputs: 50V
Output Clamp Diodes
Inputs Compatible with Popular Logic Types
Relay Driver Applications
“Green” Molding Compound (No Br, Sb)
Totally Lead-Free & Fully RoHS Compliant (Note 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
