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.
1. Minimum DC voltage on input or I/O pins is –0.5
