Notes: 1. Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings”
may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other
conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device reliability. Refer also to the SGS-THOMSON SURE Program and other
relevant quality documents.
2. Minimum Voltage may undershoot to –2V during transition and for less than 20ns.
3. Maximum DC voltage on I/O is VCC + 0.5V, overshoot to 7V allowed for less than 20ns.
