Electrical characteristics
Parameter conditions
Unless otherwise specified, all voltages are referred to V
Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at T
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
Typical values
Unless otherwise specified, typical data are based on T

They are given only as design guidelines and are not tested.
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
