This device contains protection
circuitry to guard against damage
due to high static voltages or elec-
tric fields. However, precautions
must be taken to avoid applications
of any voltage higher than maxim-
um rated voltages to this high−im-
pedance circuit. For proper opera-
tion, V_in and V_out should be con-
strained 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). Un-
used outputs must be left open.
ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ _{** Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or}
conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute−maximum−rated conditions is
not implied.
