Darlington ArrayDriver ICInductive Load

The ULN2004N is a 7-channel Darlington transistor array optimized for driving inductive loads like relays and lamps from 6V-15V CMOS logic.

Best for

  • Relay driving
  • Inductive load switching
  • CMOS-to-high-current interfacing

Avoid if

  • Driving loads requiring >500mA per channel
  • Low-voltage TTL logic (use ULN2003 instead)

Check before use

  • Thermal dissipation limits
  • Input voltage levels
