NSi8140/NSi8141/NSi8142: High Relia  
bility Quad-Channel Digital Isolators  
Datasheet (EN) 1.2  
SOIC-16 narrow body  
SOIC-16 wide body  
Product Overview  
The NSi814x devices are high reliability quad-  
channel digital isolators. The NSi814x device is  
safety certified by UL1577 support several  
insulation withstand voltages (3.75kVrms,  
5kVrms), while providing high electromagnetic  
immunity and low emissions at low power  
consumption. The data rate of the NSi814x is up to  
150Mbps, and the common-mode transient  
immunity (CMTI) is up to 150kV/us. The NSi814x  
device provides digital channel direction  
configuration and the default output level  
configuration when the input power is lost. Wide  
supply voltage of the NSi814x 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.  
AEC-Q100 (Grade 1) option is provided for all  
devices.  
Safety Regulatory Approvals (pending)  
UL recognition: up to 5000VRMS for 1 minute  
per UL1577  
CQC certification per GB4943.1-2011  
CSA component notice 5A approval  
IEC60950-1 standard  
DIN VDE V 0884-10 (VDE V 0884-10): 2006-  
12
