DC Electrical Characteristics
(Continued)
Note 4:
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 Ports).
Note 5:
Parameter is characterized but not tested in production.

, temperature and voltage levels.
Note 7:
Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
Note 8:
Guaranteed by Design.
AC Electrical Characteristics
Note 9:
Guaranteed by Design.
Note 10:
This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On Resis-
tance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
