Absolute maximum ratings are stress ratings only, and functional operation at the maxima is
not guaranteed. Continued operation at these levels may affect device reliability or cause
permanent damage to the device.
This device contains circuitry protecting against damage due to high static voltage or
electrical fields; however, it is advised that normal precautions be taken to avoid application of
any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of
operation is enhanced if unused inputs are tied to an appropriate logic voltage level (V
EV
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 EV
and operating maximum current conditions. If positive injection current (V

going out of regulation. Ensure external EV
injection current. This is the greatest risk when the MCU is not consuming power (ex; no
clock). Power supply must maintain regulation within operating EV
