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.
