NSi822x  
High Reliability  
Dual-Channel Digital Isolators  
Datasheet (EN) 1.6  
CQC certification per GB4943.1-2011  
CSA component notice 5A  
Product Overview  
The NSi822x devices are high reliability dual-channel  
digital isolators. The NSi822x device is safety certified by  
UL1577 support several insulation withstand voltages  
(3.75kVrms, 5kVrms, 8kVrms), while providing high  
electromagnetic immunity and low emissions at low  
power consumption. The data rate of the NSi822x is up  
to 150Mbps, and the common-mode transient immunity  
(CMTI) is up to 250kV/us. The NSi822x device provides  
digital channel direction configuration and the default  
output level configuration when the input power is lost.  
Wide supply voltage of the NSi822x device support to  
connect with most digital interface directly, easy to do  
the level shift. High system level EMC performance  
enhance reliability and stability of use.
