Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range
(Topr) may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or
open mode) when such damage is suffered. The implementation of a physical safety measure such as a fuse
should be considered when use of the IC in a special mode when the absolute maximum ratings may be exceeded
is anticipated.
