Questions buyers ask
- Can ULN2003 replace ULN2003?
- ULN2003 is I-CORE's functional equivalent of ULN2003 in the same SOP-16 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of ULN2003?
- Supply: See datasheet. Operating temperature: See datasheet. See the datasheet for full electrical characteristics.
- Is ULN2003 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet ULN2003-AX-QT-N085EN (revision 2026-09-A2). The full datasheet PDF is linked above.
General description
ULN2003 is high voltage, high current darlington arrays each containing seven open collector darlington pairs with common emitters. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. These versatile devices are useful for driving a wide range of loads including solenoids, relays DC motors, LED displays filament lamps, stepper motor drive and high power buffers. Each channel rated at 500mA,The Darlington tube can be connected in parallel to achieve higher output current capability. Each Darlington tube in ULN2003 is connected with a 2.7K base resistance in series. It can be directly connected with TTL/CMOS circuit at 5V working voltage, and can directly process data that originally required standard logic buffer to process.
Key features
- Output current 500mA per driver
- Output voltage 50V
- TTL/CMOS compatible inputs
