Product Introduction

Overview

The ULN2003ADRE4 is a high-voltage, high-current Darlington transistor array produced by Texas Instruments. This component is part of the ULN2003 series, which includes seven open collector Darlington pairs with common emitters. It is designed to handle a wide range of loads, including solenoids, relay DC motors, LED displays, filament lamps, and thermal printheads. The ULN2003ADRE4 is particularly useful for applications requiring high current and voltage capabilities, and it is compatible with various logic families such as TTL, CMOS, PMOS, and DTL.
