5.1
Maximum Ratings
Table 5. Absolute Maximum Ratings1, 2
1 Functional operating conditions are given in Section 5.4, “DC Electrical Specifications.” 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.
2 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 VSS or EVDD).

calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.

Instantaneous Maximum Current
Single pin limit (applies to all pins) 3, 4, 5
4 All functional non-supply pins are internally clamped to V
SS and EVDD.
5 Power supply must maintain regulation within operating EV
DD range during instantaneous and operating maximum
current conditions. If positive injection current (Vin > EVDD) is greater than IDD, the injection current may flow out of
EVDD and could result in external power supply going out of regulation. Insure external EVDD load will shunt current
greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power (ex; no
clock). Power supply must maintain regulation within operating EVDD range during instantaneous and operating
maximum current conditions.
