7 ELECTRICAL CHARACTERISTICS
7.1 ABSOLUTE MAXIMUM RATINGS
Devices of the ST72 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 V
strained within the range:
To enhance reliability of operation, it is recom-
mended to configure unused I/Os as inputs and to
