(1)
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.
(2)
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
(3)
The value of VCCA and VCCB are provided in the recommended operating conditions table.
(4)
The package thermal impedance is calculated in accordance with JESD 51-7.

(1)
VCCI is the supply voltage associated with the input port.
(2)
VCCO is the supply voltage associated with the output port.
(3)
VCCA must be less than or equal to VCCB, and VCCA must not exceed 3.6 V.
(4)
The maximum VIL value is provided to ensure that a valid VOL is maintained. The VOL value is VIL plus the voltage drop across the
pass-gate transistor.
