The NSI823x devices are high reliability triple-channel digital isolators. The NSI823x device is safety certified by UL1577 support several insulation withstand voltages (3kVrms, 3.75kVrms, 5kVrms, 8kVrms), while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSI823x is up to 150Mbps, and the common-mode transient immunity (CMTI) is up to 250kV/μs. The NSI823x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage of the NSI823x device supports to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use.
