Product Description

Product Overview

The ULN2003 is a high-voltage, high-current Darlington transistor array featuring seven open-collector, common-emitter pairs. Each pair is rated at 500mA and includes suppression diodes for inductive load driving. The inputs and outputs are arranged for simplified board layout, making it suitable for driving a wide range of loads such as solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads, and high-power buffers. Available in DIP-16, SOP16, and TSSOP16 packages.
