Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any
of these limits are exceeded, device functionality should not be assumed, damage may occur
and reliability may be affected.

Functional operation above the stresses listed in the Recommended Operating Ranges is not
implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may
affect device reliability.
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance cir-
cuit. For proper operation, V_in and
V_out should be constrained to the
range GND v (V_in or V_out) v V_CC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V_CC).
Unused outputs must be left open.
