NOTE:
This device contains circuitry designed to protect against damage due to
high electrostatic voltages or electric fields. However, it is recommended
that normal precautions be taken to avoid the application of any voltages
higher than those given in the Maximum Ratings table to this high
impedance circuit. For maximum reliability all unused inputs should be
tied to either V_SS or V_DD.
