H11N2

Logic Output Optoisolators Overview

The onsemi H11N2 is a discontinued single-channel logic output optoisolator featuring an open collector NPN transistor output. It provides a high isolation voltage of 7500Vrms and supports data rates up to 5MHz. The device utilizes a DC input with a typical forward voltage of 1.4V and a maximum DC forward current of 30mA. It offers a channel-to-channel common-mode transient immunity (CMTI) and operates within a temperature range of -40°C to 85°C. Packaged in a 6-SMD surface-mount configuration, it delivers a maximum output current of 50mA per channel.
