Notes:

Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation at or above this specification is not implied.
Exposure to maximum rating conditions for extended periods may affect device reliability.
Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky
diode clamps from input pin to the supplies. All inputs have protection diodes which will protect the
device from short transients outside the supplies of less than 100mA for less than 100ms.
