ULN2003AI - High-Current Darlington Transistor Arrays

This page provides the datasheet information for the ULN2003AI, a member of the ULN2002A High-Current Darlington Transistor Arrays family.

Description

The ULx200xA devices are high-voltage, high-current Darlington transistor arrays.

Each consists of 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 is 500mA.

Features

  • 500mA-rated collector current (single output).
  • High-voltage outputs: 50V.
  • Output clamp diodes.
  • Inputs compatible with various types of logic.
  • Relay-driver.
