NOTES:

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 (VSS or

EVDD).

3 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.

4 All functional non-supply pins are internally clamped to VSS and EVDD.

5 Power supply must maintain regulation within operating EVDD 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. Ensure external EVDD load shunts current greater than maximum

injection current. This is 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.
