Notes:
Stresses above those listed under “Absolute Maximum

This is
1. Minimum DC voltage on input or I/O pins is –0.5
V. During voltage transitions, input or I/O pins
may overshoot VSS to
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.
