Figure 2. Block Diagram
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that
normal precautions be taken to avoid application 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.
