11 ELECTRICAL CHARACTERISTICS
11.1 Parameter Conditions
Unless otherwise specified, all voltages are
referred to V
11.1.1 Minimum and Maximum values.
Unless otherwise specified, the minimum and
maximum values are guaranteed in the worst
conditions of environment temperature, supply
voltage and frequencies production testing on
100% of the devices with an environmental
temperature at T
the selected temperature range).
Data is based on characterization results, design
simulation and/or technology characteristics are
indicated in the table footnotes and are not tested
in production. The minimum and maximum values
are based on characterization and refer to sample
tests, representing the mean value plus or minus
three times the standard deviation (mean 3 ).
11.1.2 Typical values.
Unless otherwise specified, typical data is based
on T
voltage range). They are provided only as design
guidelines and are not tested.
11.1.3 Typical curves.
Unless otherwise specified, all typical curves are
provided only as design guidelines and are not
tested.

11.2 Absolute Maximum Ratings
Stresses above those listed as “absolute maximum
ratings” may cause permanent damage to the
device. This is a stress rating only.
Functional operation of the device under these
conditions is not implied. Exposure to maximum
rating conditions for extended periods may affect
device reliability.
