Product Overview
The NSi824xC devices are high reliability quad-channel
digital isolators. The NSi824xC device is safety certified by
UL1577 support 5kV insulations withstand voltage, while
providing high electromagnetic immunity and low
emissions at low power consumption. The data rate of the
NSi824xC is up to 100Mbps, and the common-mode
transient immunity (CMTI) is up to 150kV/us. The NSi824xC
device provides digital channel direction configuration and
the default output level configuration when the input
power is lost. Wide supply voltage of the NSi824xC 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.
