DC Electrical Characteristics
(Continued)
Note 4: Measured by the voltage drop between A and B
n
pins at the indicated current through the switch. On Resistance is determined by the lower of the voltages on the two (A
or B
n
Ports).
Note 5: Parameter is characterized but not tested in production.

Note 7: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
AC Electrical Characteristics
Note 8: This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On Resistance of the switch and
the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
Note 9: Guaranteed by Design.
