1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
3101 drw 03
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 is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect
reliability.
2. Input, Output, and I/O terminals; 4.6V maximum.
