Maximum Ratings
(Voltages referenced to V
SS
)
This device contains circuitry to protect the inputs against damage due to high static
voltages or electric fields; however, it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum-rated voltages to this high-impedance
circuit. For proper operation, it is recommended that V
IN
and V
OUT
be constrained to the
range V
SS
(V
IN
or V
OUT
)
V
DD
. Reliability of operation is enhanced if unused inputs are
connected to an appropriate logic voltage level (e.g., either V
SS
or V
DD
).
