Note 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.
Note 2: The input and output negative-voltage ratings may be exceeded if the input and output
current ratings are observed.
Note 3: The value of V_CCA and V_CCB are provided in the recommended operating conditions table.

Note 1: The A and B sides of an unused data I/O pair must be held in the same state, i.e., both at
V_CCI or both at GND.
Note 2: V_CCA must be less than or equal to V_CCB and must not exceed 3.6 V.
Note 3: V_CCI is the supply voltage associated with the input port.
