Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Description section 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 VCI and VOUT be constrained to the range VSS < VDDIO ≤ VCI < VOUT. Reliability of operation is enhanced if unused input is connected to an appropriate logic voltage level (e.g., either VSS or VDDIO). Unused outputs must be left open. This device may be light sensitive. Caution should be taken to avoid exposure of this device to any light source during normal operation.
