Maximum is highest voltage that POR is guaranteed.
2
RAM will retain data down to POR voltage. RAM data not guaranteed to be valid following a POR.

Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
resistance values for positive and negative clamp voltages, then use the larger of the two values.
