voltages may cause damage. Laboratory testing has shown that this type of protection is
not necessary under normal conditions. However, damage may occur under harsh
conditions or when subjected to unusual abuse. Also note, the protection circuit shown

it is not powered up. If this is a concern, then another protection circuit must be
designed.
