Product Overview

The NSi812x devices are high reliability dual-channel digital isolators offering safety certification (UL1577) with various insulation withstand voltages (3.75kVrms, 5kVrms). They provide high electromagnetic immunity, low emissions, and low power consumption. With data rates up to 150Mbps and common-mode transient immunity (CMTI) up to 150kV/us, these isolators feature configurable digital channel direction and default output levels upon power loss. Their wide supply voltage range allows direct connection to most digital interfaces for easy level shifting, enhancing system reliability and stability through high EMC performance. An AEC-Q100 (Grade 1) option is available for 3.75kV parts.
