(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 V_CCA and V_CCB are provided in the recommended operating conditions table.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

(1) V_CCI is the supply voltage associated with the input port.
(2) V_CCO is the supply voltage associated with the output port.
(3) V_CCA must be less than or equal to V_CCB, and V_CCA must not exceed 3.6 V.
(4) The maximum V_IL value is provided to ensure that a valid V_OL is maintained. The V_OL value is V_IL plus the voltage drop across the pass-
gate transistor.
