NOTE

Stresses exceeding the recommended absolute maximum ratings may cause permanent

damage to the device. This is a stress rating only and functional operation of the device at

these or any other conditions above those indicated in the operational sections of this

specification are not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability. During overload conditions (VIN >VDD or

VIN <VSS), the voltage on pins with respect to ground (VSS) must not exceed the

recommended values.
