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.
