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).

UG130: Si86xxT-EVB User's Guide Hardware Setup and Demonstration 3. Hardware Setup and Demonstration 3.1 Powering the Supplies Both sides of the Si8642ET isolator accept supplies between 2.5-5.5 V. See the figure below. Perform the following steps to set up the Si864xxT-EVB: •... - Page 5 UG130: Si86xxT-EVB User's Guide Hardware Setup and Demonstration 3.2.2 Fail-safes When power is removed from one side of the isolator, the outputs at the other side of the isolator default to logic High. • A-side • Remove all shunts. • Remove A-side power supply.
- Page 6 UG130: Si86xxT-EVB User's Guide Hardware Setup and Demonstration 3.2.3 Configured For an example, see the figure below. • Place a shunt across J1 at A2. • This produces a logic Low input on forward channel A2. The SI88642ET will transmit this to the B-side, and the corresponding logic Low can be observed and measured with the DMM on J2, B2.
