Product Overview

The NSI822x devices are high reliability dual-channel digital isolators offering robust insulation withstand voltages (up to 5kVrms), high electromagnetic immunity, and low power consumption. They support data rates up to 150Mbps and provide common-mode transient immunity (CMTI) of up to 250kV/us. These isolators allow for digital channel direction configuration and default output level configuration during power loss. Their wide supply voltage range facilitates direct connection with most digital interfaces, enabling easy level shifting. Enhanced system-level EMC performance ensures reliability and stability. An AEC-Q100 (Grade 1) option is available for all devices.
