Measured with V
All functional non-supply pins are internally clamped to V
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.
Power supply must maintain regulation within operating V
current conditions. If positive injection current (V

Examples are: if no system clock is present, or if clock rate is very low (which would reduce overall power
consumption).
Maximum is highest voltage that POR is guaranteed.
