Very seldom you'll find true 5V tolerance, the die must have thicker oxide. And no clamp diodes, of course.
Usually it is this type of dependence on previously biased something (Vdd >= xxx). Random example:

Check page 51.
Most datasheets are overly murky on details and do not stress this enough, and there is abundance of designs as if it was true 5V tolerance.
The magic window during ramping slowly eats the poor oxide away.
