ULN2003AN IC DIP16 TI 2003 ULN2003AN

Product Overview

The ULN2003AN is a high-voltage, high-current Darlington transistor array designed to interface low-level logic circuits with higher-power loads. It consists of seven independent npn Darlington pairs featuring high-voltage outputs with common-cathode clamp diodes for switching inductive loads. This device is commonly used to drive relays, lamps, solenoids, small motors, and other demanding electrical loads from standard microcontrollers or logic families.
