Refers to common-mode transients across the insulation barrier. Common-

mode transients exceeding the Absolute Maximum Ratings can cause latch-

up or permanent damage.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
