Absolute Maximum Ratings[6]
This device contains circuitry to protect the input against
damage due to high static voltages or electric fields; however,
precautions should be taken to avoid application of any
voltage higher than the absolute maximum rated voltages to
this circuit. For proper operation, VIN and VOUT should be
constrained to the range, VSS < (VIN or VOUT) < VDD. All digital
inputs are tied high or low internally. Refers to electrical speci-
fications for operating supply range.
