ULN2003GDarlington array7-channel driverlow-side switchinductive load driverSOP-16

ULN2003G is a seven-channel SOP-16 Darlington low-side driver for relay, lamp, solenoid and motor loads, with integrated clamp diodes.

Best for

  • Multi-channel relay and solenoid drive
  • Stepper-motor coil switching
  • Logic-controlled low-side inductive loads

Avoid if

  • Applications requiring very low output voltage drop
  • Loads exceeding the stated channel current or voltage ratings
  • Designs requiring confirmed compliance or lifecycle information

Check before use

  • Confirm the temperature range applicable to the selected device revision
  • Calculate power dissipation from output saturation voltage and load current
  • Verify COM connection to the positive inductive-load supply
