consumption. The data rate of the NSi812x is up to
150Mbps, and the common-mode transient
immunity (CMTI) is up to 150kV/us. The NSi812x
device provides digital channel direction
configuration and the default output level
configuration when the input power is lost. Wide
supply voltage of the NSi812x 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 3.75kV
parts.
