Note 1:
Signals on COM or NO_ exceeding V+ or GND are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

6:
Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over
the specified analog signal ranges.
7:
Leakage parameters are 100% tested at hot temperature and guaranteed by correlation at room temperature.
