Product Introduction

Overview

The ULN2064B is a high-voltage, high-current Darlington array manufactured by STMicroelectronics. It is designed to interface low-level logic signals with a variety of high current, high voltage loads. Each device contains four NPN Darlington switches, capable of delivering up to 1.5 A with a minimum breakdown voltage of 50 V and a sustaining voltage of 35 V measured at 100 mA. The ULN2064B is particularly useful for driving loads such as relays, solenoids, DC and stepper motors, magnetic print hammers, and multiplexed LED and incandescent displays.
