Product Description

Product Overview

The ULN2002D is a monolithic integrated high voltage, high current Darlington array IC featuring five independent Darlington drive channels. It includes a built-in freewheeling diode for driving inductive loads like relays and stepping motors. Each single Darlington tube collector can output 500 mA, with parallel connection for higher current capacity. This IC is widely used in relay drive, indicator light drive, display screen drive (LED), stepping motor drive, and as a logic buffer.
