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.
