Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance
is determined by the lower of the voltages on the A or B pins.

Note:
4.
This parameter is guaranteed by design, but is not tested. The bus switch contributes no propagation delay
other than the RC delay of the typical on resistance of the switch and the 50pF load capacitance when driven by
an ideal voltage source (zero output impedance).
