NSi823x-Q1
High Reliability Reinforced
Triple-Channel Digital Isolators
Datasheet (EN) 1.1
Product Overview
Safety Regulatory Approvals
The NSi823x devices are high reliability triple-channel
digital isolators. The NSi823x 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 NSi823x is up to 150Mbps, and the common-mode
transient immunity (CMTI) is up to 250kV/us. The NSi823x
device provides digital channel direction configuration
and the default output level configuration when the
input power is lost. Wide supply voltage of the NSi823x
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.
AEC-Q100 (Grade 1) option is provided for all devices.
