ESD CAUTION
1 Rating assumes VDD1 is above 2.5 V. VI+ and VI− are rated up to 6.5 V when VDD1 is unpowered. 2 Referenced to GND2, maximum of 40 V. 3 |CM| refers to common-mode transients across the insulation barrier. Common-mode transients exceeding the absolute maximum rating can 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.
