Maximum rating
Stressing the device above the rating listed in the Absolute Maximum Ratings table may cause permanent damage to the device. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. 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. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
Absolute Maximum Ratings
| Symbol | Parameter | Min | Max | Unit |
| TBIAS | Temperature Under Bias | –50 | 125 | °C |
| TSTG | Storage Temperature | -65 | 150 | °C |
| VIO | Input or Output Voltage(1)(2) | –0.6 | VCC +0.6 | V |
| VCC | Supply Voltage | –0.6 | 4 | V |
| VID | Identification Voltage | –0.6 | 13.5 | V |
| VPP (3) | Program Voltage | –0.6 | 13.5 | V |
1. Minimum voltage may undershoot to –2V during transition and for less than 20ns during transitions.
2. Maximum voltage may overshoot to VCC +2V during transition and for less than 20ns during transitions.
3. VPP must not remain at 12V for more than a total of 80hrs.
