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.

4. ESD Ratings

When a statically-charged person or object touches an electrostatic discharge sensitive device, the electrostatic

charge might be drained through sensitive circuitry in the device. If the electrostatic discharge possesses

sufficient energy, damage might occur to the device due to localized overheating.
