These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.

(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) _{All voltages are with respect to ground of this device except VCn-VC(n+1), where n = 1, 2, 3, 4 cell voltage.}
(3) _{Design considerations should be made with respect to excessive ESD.}
