Information in this section is based on the datasheet of the repeaters IC (FIN1101K8X\footnote{\label{repeaters}https://www.onsemi.com/pdf/datasheet/fin1101-d.pdf}).
The Absolute Maximum Ratings are those values beyond which damage to the device may occur.
Other specifications should be met without exception.
