ULN2003ANS Description

Short technical summary and product information.

The ULN2003ANS from Texas Instruments is a versatile Darlington transistor array designed for high-voltage and high-current applications. Each device contains seven NPN Darlington pairs, each capable of handling a 500mA collector current and 50V output voltage. The integrated common-cathode clamp diodes are crucial for effectively switching inductive loads, making this component ideal for various driver applications.

 

This array is designed for direct compatibility with TTL or 5V CMOS devices, featuring a 2.7kΩ series base resistor for each Darlington pair. Its applications span across relay drivers, stepper and DC brushed motor drivers, lamp drivers, and display drivers (LED and gas discharge). The ULN2003ANS is available in a 16-SOIC package, suitable for surface mount applications.

 

Key electrical characteristics include a typical output voltage of 50V, a maximum collector current of 500mA per output, and a typical delay time of 250ns. The operating temperature range is from -40°C to 70°C. The parallel interface and inverting input type offer flexibility in system integration.
