MAXIMUM RATING

Stressing the device above the rating listed in the

Absolute Maximum Ratings” table may cause per-

manent 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 im-

plied. Exposure to Absolute Maximum Rating con-

ditions for extended periods may affect device

reliability. Refer also to the STMicroelectronics

SURE Program and other relevant quality docu-

ments.
