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 V
