This device contains circuitry to protect

against damage due to high static voltages or

electric fields; however, it is advised that

normal precautions be taken to avoid applica-

tion of any voltage higher than maximum rated

voltages to this high impedance circuit. For

proper operation it is recommended that Vin

andVout be constrained to the range VSS (Vin

or Vout) VDD.

Unused inputs must always be tied to an

appropriatelogic voltage level (e.g., VSS,VDD,

VLS, or VAG).
