Stressing the device outside the ratings listed in <Blue>Table 5. may cause permanent
damage to the device. These are stress ratings only, and operation of the device at these, or
any other conditions outside 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 STMicroelectronics SURE Program and other
relevant quality documents.

5 DC and AC parameters
This section summarizes the operating and measurement conditions, and the DC and AC
characteristics of the device. The parameters in the DC and AC Characteristic tables that
follow are derived from tests performed under the Measurement Conditions summarized in
the relevant tables. Designers should check that the operating conditions in their circuit
match the measurement conditions when relying on the quoted parameters.
