ULN2803ANDarlington array8-channel driveropen collectorinductive load driverDIP-18

ULN2803AN-JSM is an 8-channel low-side Darlington driver for switching relays, solenoids, motors, lamps, and similar loads up to 50 V and 500 mA per output.

Best for

  • Multi-channel relay and solenoid drivers
  • Low-side switching of inductive loads
  • Through-hole control boards

Avoid if

  • Low voltage-drop switching is required
  • Load current exceeds 500 mA per channel
  • A surface-mount package is required

Check before use

  • Connect pin 9 common emitter to ground
  • Connect pin 10 COM to the inductive-load supply when clamp diodes are used
  • Calculate thermal dissipation from saturation voltage and load current
