Note:

If Input/Output terminals voltage over the absolute maximum ratings, there is possibility of mis-operation,

characteristics deterioration and destruction, because of the current’s flowing to parasitic diode in IC.

The Input/Output terminals are recommended to be protected with the clamp circuit which using the diode with

low forward voltage (like schottky barrier diode) when there is a possibility for the Input/Output terminals

voltage exceeds the absolute maximum ratings.
