Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the absolute maximum ratings may cause
latch-up or permanent damage.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.

those standards.
