NSi823xC
High Reliability Reinforced
Triple-Channel Digital Isolators
Datasheet (EN) 1.2
Product Overview
Safety Regulatory Approvals
The NSi823xC devices are high reliability triple-channel
digital isolators. The NSi823xC device is safety certified
by UL1577 support 5kVrms insulation withstand voltage,
while providing high electromagnetic immunity and low
emissions at low power consumption. The data rate of
the NSi823xC is up to 150Mbps, and the common-mode
transient immunity (CMTI) is up to 250kV/us. The
NSi823xC device provides digital channel direction
configuration and the default output level configuration
when the input power is lost. Wide supply voltage of the
NSi823xC 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.
