In the commenrcial product datasheet, it always gives the "absolute maximum rating" which describe the risks when the product operate exceeeding this limt.
My question is mainly focused on the definitions on the maximum absolute ratings of the supply voltage and input(output) voltage.
I do understand a too high supply voltage could cause an accelerated wear out of devices and a too high and sustained input voltage could cause permanent damage to ESD structures, etc... "
But I have no idea how to quantitatively define it. E.g., how can I know at what high supply will cause an accelerated wear out of devices? Also, I understand too high and sustained input voltage will cause the permanent damage to ESD structures. But I can not know how high this input voltage will have this risks.
Any guidelines to quantitatively define it?
Thanks in advance
