Absolute Maximum Ratings

Note: T

Stresses above those listed in Table 6

“Absolute Maximum Ratings” may cause permanent damage to the

device. These are absolute stress ratings only and operation of the device is not implied or recommended at

these or any other conditions in excess of those given in the operational sections of this specification. Exposure

over values of the recommended ratings (Table 8) for extended periods may adversely affect the operation and

reliability of the device.
