Product Description
Product Overview
The NSI802x devices are high reliability dual-channel digital isolators designed for demanding applications. They offer robust 3kVrms insulation withstand voltages certified by UL1577, ensuring high electromagnetic immunity and low emissions with minimal power consumption. With data rates up to 10Mbps and common-mode transient immunity (CMTI) up to 100kV/us, these isolators provide reliable digital channel direction and default output level configuration during power loss. Their wide supply voltage range simplifies level shifting, and their high system-level EMC performance enhances overall reliability and stability.
