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 under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
The package thermal impedance is calculated in accordance with JESD 51-7.

All typical values are at VCC = 5 V (unless otherwise noted), TA = 25°C.
Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is
determined by the lower voltage of the two (A or B) terminals.
