Measured by the voltage drop between I/O pins at the indicated current through the switch. ON resistance is determined by the lower of the
voltages on the two (A or B) ports.

This parameter is characterized, but not tested in production.
Flatness is defined as the difference between the maximum and minimum values of ON resistance over the specified range of conditions.
