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.
All voltages are with respect to ground of this device except VCn-VC(n+1), where n=1, 2, 3, 4 cell voltage.
