Note 1: 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 limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” 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 4: On Resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
Note 5: 'RON RONmax RONmin measured at identical VCC, temperature, and voltage.
Note 6: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
