6. 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 two (A or B) pins.

7. 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 source (zero output impedance).
