ST ULN2001 ULN2002 ULN2003 ULN2004 handbook
This document provides production data for the ULN2001, ULN2002, ULN2003, and ULN2004 high voltage, high current Darlington arrays. Each device contains seven open collector Darlington pairs with common emitters, rated at 500 mA continuous collector current and capable of withstanding peak currents of 600 mA. The arrays include integrated suppression diodes for driving inductive loads and feature inputs pinned opposite to outputs to simplify board layout.
The datasheet details the specific characteristics for four versions compatible with various logic families: ULN2001 for general purpose (DTL, TTL, PMOS, CMOS), ULN2002 for 14-25 V PMOS, ULN2003 for 5 V TTL/CMOS, and ULN2004 for 6-15 V CMOS/PMOS. Available in DIP-16 and SO-16 packages, these devices are designed for driving solenoids, relays, DC motors, LED displays, filament lamps, and thermal printheads.
