ULQ2004AN - High-Current Darlington Transistor Arrays

Download the ULQ2004AN datasheet PDF. This datasheet also covers the ULQ2003A variant, as both devices belong to the same high-current darlington transistor arrays family and are provided as variant models within a single manufacturer datasheet.

General 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 500 mA.

Key Features

  • 1 500-mA-Rated Collector Current (Single Output).
  • High-Voltage Outputs: 50 V.
  • Output Clamp Diodes.
  • Inputs Compatible With Various Types of Logic.
  • Relay-Driver.
