DESCRIPTION

Description

OVERVIEW

Product Overview

The ULN2803ADWR is an eight-channel Darlington transistor array from Texas Instruments. It integrates multiple Darlington pairs and can drive relays, solenoids, LED indicators and small motors. It is usually used with logic circuits, accepting low-level control signals and sinking larger currents, acting as an interface between the control side and the load side. It is commonly found in industrial control, consumer electronics, office equipment and automation devices. When purchasing, verify the package, batch and packaging; refer to the original datasheet for specific electrical parameters and temperature ranges.

APPLICATIONS

Applications

  • Used to drive relays and solenoids.
  • Used to drive LED indicators and display segments.
  • Used for switching control of small motors and actuators.
  • Used as load interfaces in industrial control and office equipment.
FEATURES AND BENEFITS

Features and Benefits

  • Eight Darlington outputs can drive multiple loads simultaneously.
  • Suitable for accepting logic-level control signals and driving higher-current loads.
  • Integrated flyback diode structure facilitates connecting inductive loads.
  • Standard package facilitates replacement in existing driver circuits.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify the model suffix, package, batch and packaging, and confirm the number of output channels matches the target load.
