Product Specifications

  • IC number: ULN2003
  • Function: Darlington Transistor Array
  • Number of pins: 16
  • Pin type: DIP
  • package contains: 1 piece of ULN2003 IC unused


  • The ULN2003A is a high-voltage, high-current Darlington transistor arrays device.
  • Each IC or chip has seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
  • The collector-current rating of a single Darlington pair: – 500 mA.
  • We can parallel The Darlington pair to get the high current capability.
  • Applications of ULN2003: – relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
  • The ULN2002A IC is specifically designed for use with 14-V to 25-V PMOS devices.
  • To control the input current to a safe limit, each input of ULN2003 has resistor and Zener diode.
  • The ULN2003A has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices.
