Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. VrampHL and Vcl are the internal clamp levels of pins 4 and 5 respectively.
2. The maximum junction temperature should not be exceeded.
