2. Absolute Maximum Ratings

Exceeding the maximum ratings listed under Absolute Maximum Ratings when designing is likely to damage the

device permanently. Do not design to the maximum limits because long-time exposure to them might impact the

device’s reliability. The ratings are obtained over an operating free-air temperature range unless otherwise

specified.
