ages or electric fields; however, it is advised that
normal precautions be taken to avoid applica-
tions of any voltage higher than the maximum
rated voltages to this high impedance circuit.
For proper operation it is recommended that
Vin and Vout be constrained to the range VSS
≤
(Vin or Vout)
≤
VDD. Reliability of operation is
enhanced if unused inputs are tied to and
appropriate logic voltage level (e.g., either VSS
or VDD).
