7 ELECTRICAL CHARACTERISTICS
7.1 ABSOLUTE MAXIMUM RATINGS
Devices of the ST 72 family contain circuitry to pro-
tect the inputs against damage due to high static
voltage or electric fields. Nevertheless, it is recom-
mended that normal precautions be observed in
order to avoid subjecting this high-impedance cir-
cuit to voltages above those quoted in the Abso-
lute Maximum Ratings. For proper operation, it is
recommended that the input voltage VIN be con-
strained within the range:
(VSS - 0.3V) ≤ VIN ≤ (VDD + 0.3V)
To enhance reliability of operation, it is recom-
mended to configure unused I/Os as inputs and to
connect them to an appropriate logic voltage level
such as VSS or VDD. it is also recommended to
connect VDDA and VDD together on application.
(same remark for VSSA and VSS).
All the voltage in the following tables are refer-
enced to VSS.
Stresses above those listed as “Absolute Maxi-
mum Ratings” may cause permanent damage to
the device. Functional operation of the device at
these conditions is not implied. Exposure to maxi-
mum rating conditions for extended periods may
affect device reliability.
