Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum
Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress
beyond those listed 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 (e.g., either V
Input must be current limited to the I
current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then
use the larger of the two values.
All functional non-supply pins are internally clamped to V
Power supply must maintain regulation within operating V
operating maximum current conditions. If positive injection current (V
the injection current may flow out of V
regulation. Insure external V
will be the greatest risk when the MCU is not consuming power (ex; no clock).Power supply must
maintain regulation within operating V
current conditions.
