DESCRIPTION

Description

OVERVIEW

Product Overview

The ULN2003A is a Darlington transistor array IC commonly used in applications requiring multiple high-current driving channels. It integrates several Darlington pairs, each typically including a flyback diode, for driving inductive loads such as relays, solenoids, stepper motors, and small DC motors. Its inputs can interface directly with logic levels, simplifying the drive design between microcontrollers and loads. As original manufacturer documentation is not provided, this description does not include specific voltage, current, power, or certification details.
