NSi824xC

High Reliability Reinforced

Quad-Channel Digital Isolators

Datasheet (EN) 1.1

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.
