2 ELECTRICAL CHARACTERISTICS
2.1 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 V
IN
and V
OUT
be constrained
within the range:
V
SS
≤
V
IN
and V
OUT
≤
V
DD
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 V
SS
or V
DD
.
All the voltage in the following tables are refer-
enced to V
SS
.
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.
