STM6904 Maximum rating
Doc ID 14289 Rev 3 11/20
5 Maximum rating
Stressing the device above the rating listed in Table 3: 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 Section 6: DC and AC
parameters of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Refer also to the
STMicroelectronics™ SURE Program and other relevant quality documents.
