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.
