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 appli-
cation of any voltage higher than 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.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., VBB,
GNDA, or VCC).
