Table 2. Absolute Maximum Ratings
(1)
Note: 1. Except for the rating ”O(jiān)perating 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 condi-
tions forextended periods may affect device reliability. Referalso to theSTMicroelectronics SURE Program and other relevantqual-
ity documents.
2. Minimum Voltage may undershoot to –2V during transition and for less than 20ns during transitions.
