ULN2803AN-TD is an 8-channel Darlington low-side driver for relays, solenoids, lamps, and motor windings. It supports up to 50 V outputs and 500 mA maximum collector current per channel.

Best for

  • Relay and solenoid low-side drivers
  • Stepper-motor winding drivers
  • TTL or 5 V CMOS controlled loads

Avoid if

  • The load requires high-side switching
  • A channel must source current
  • Compliance status must be documented

Check before use

  • Verify exact ULN2803AN-TD package ordering
  • Observe per-channel current and thermal limits
  • Use COM for inductive-load clamp diodes
