(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are with respect to network ground terminal, unless specified otherwise.
(3) IVCC5 is not specifying VCC5 output current capability for external load. The allowed external load on VCC5 is specified at position 3.18 in Recommended Operating Conditions.
