11 ELECTRICAL CHARACTERISTICS

11.1 Parameter Conditions

Unless otherwise specified, all voltages are

referred to Vss.

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 TA=25°C and TA=TAmax (given by

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

±3Σ).

11.1.2 Typical values.

Unless otherwise specified, typical data is based

on TA=25°C, VDD=5V (for the 4.5≤VDD≤5.5V

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.

Figure 11.1 Pin loading conditions

11.1.4 Loading capacitor. The loading condition

used for pin parameter measurement is illustrated

in Figure 11.1.

11.1.5 Pin input voltage.

Input voltage measurement on a pin of the device

is described in Figure 11.2

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.
