Product Description

Product Overview

The NSi812x devices are high reliability dual-channel digital isolators offering safety certification (UL1577) with high insulation withstand voltages (3.75kVrms, 5kVrms). They provide excellent 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 ensure reliable operation. Features include configurable digital channel direction and default output levels upon power loss. The wide supply voltage range allows for direct connection to most digital interfaces, simplifying level shifting and enhancing system-level EMC performance for increased reliability and stability. An AEC-Q100 (Grade 1) option is available for 3.75kV parts.
