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.
