UG130: Si86xxT-EVB User's Guide

The Si864xxT devices, the latest addition to the Si86xx isolator family, are 4-channel
CMOS-based galvanic digital isolators surge rated at 10 kV. Operating up to 150 Mbps,
they are available in wide body 16-pin SOIC packages and designed for the stringent
isolation needs of the industrial, commercial, and automotive markets. Various channel
configurations dictating the number of reverse channels and default output states are
also available per the Si86xx data sheet’s ordering guide.

The  Si864xxT-EVB  allows  designers  to  quickly  evaluate  the  Si8642ET’s  capabilities
and functionality, either by driving inputs to logic low via shunts, or injecting signals to
the header pins via single wires or a 2x6 ribbon cable (not included).

For more information on our Si86xxT isolators, visit the Silicon Labs website at:

. The product data sheet and application notes can be refer-

enced to help facilitate designs.
