Note 2: 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 two (A or B) pins.

Note 3: 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 50 pF load capacitance, when
driven by an ideal voltage the source (zero output impedance).
