8. ELECTRICAL CHARACTERISTICS
8.1 Absolute Maximum Ratings
Notes:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the device at these or any other conditions above those
indicated in the operational sections of this data sheet is not implied. Exposure of the device to absolute maximum
rating conditions for extended periods may affect device reliability.
8.2 Operating Ranges
Operating ranges define those limits between which the functionality of the device is guaranteed.
