Note the offset of the output low level voltage from ground on SDA1 and SCL1.

In addition to the cases shown here, the SDA and SCL signals also propagate in mutually opposing directions.
However, if using ISO1541, the SCL line is unidirectional and only allows the signal to propagate from SCL1 to
SCL2 and not vice-versa.
