Note:
Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The datasheet
specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and
output/input loading variables. Pericom does not recommend operation outside datasheet specifications.
