The ULN2003A is a high-voltage, high-current Darlington transistor array.

It consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode flyback diodes for switching inductive loads.

It is very similar to the ULN2801A, ULN2802A, ULN2803A, ULN2804A, and ULN2805A, only differing in logic input levels (TTL, CMOS, PMOS) and number of inputs (8).

The drivers can be paralleled for higher current capability, even stacking one chip on top of another, both electrically and physically has been done. Generally it can also be used for interfacing with stepper motor, where the motor requires high ratings which cannot be provided by other interfacing devices.


  • 500 mA rated collector current (single output)
  • 50 V output
  • Includes output flyback diodes
  • Inputs compatible with various types of logic
