The “Absolute Maximum Ratings” are those values beyond which the safety
of the device cannot be guaranteed. The device should not be operated at these lim-
its. The parametric values defined in the Electrical Characteristics tables are not
guaranteed at the absolute maximum ratings. The “Recommended Operating Condi-
tions” table will define the conditions for actual device operation.
Note 2:
The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed.
Note 3:
Unused inputs must be held HIGH or LOW. They may not float.

Note 9:
This parameter is guaranteed by design but is not tested. The 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).
