6 ELECTRICAL CHARACTERISTICS
The ST727x4 device contains circuitry to protect
the inputs against damage due to high static
voltage or electric field. Nevertheless it is advised
to take normal precautions and to avoid applying to
this high impedance voltage circuit any voltage
higher than the maximum rated voltages. It is
recommended for proper operation that VIN and
VOUT be constrained to the range:
VSS ≤ (VIN or VOUT) ≤ VDD
To
enhance
reliability
of
operation,
it
is
recommended to connect unused inputs to an
appropriate logic voltage level such as VSS or VDD.
All the voltages in the following table, are
referenced to VSS.
