Power Distribution Switches

Darlington ArrayDriver ICHigh Current

The ULN2004A is a 7-channel Darlington transistor array designed for high-current, high-voltage load switching, specifically optimized for 6-15V CMOS and PMOS logic interfaces.

Best for

  • Relay driving
  • Solenoid control
  • DC motor switching

Avoid if

  • Logic levels are below 6V (use ULN2003 instead)
  • High-speed switching applications

Check before use

  • Thermal dissipation requirements
  • Peak current limits
