ULN2003ADR Description

Short technical summary and product information.

The Texas Instruments ULN2003ADR is a high-voltage, high-current Darlington transistor array. Each device consists of seven NPN Darlington pairs with common-cathode clamp diodes for switching inductive loads. The collector-current rating for a single Darlington pair is 500mA, and pairs can be paralleled for increased current capability.

 

Key electrical specifications include a 50V switching and output voltage, a 500mA output current per channel, and compatibility with CMOS and TTL logic inputs. The typical delay time is 250ns. The device operates within a temperature range of -40°C to 70°C.

 

This transistor array is available in a 16-SOIC surface mount package. Its applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The ULN2003ADR is suitable for driving loads such as relays, solenoids, and incandescent lamps where higher current or voltage is required than can be provided by logic outputs alone.
