1 Typical values are based on characterization data at 25
°C unless otherwise stated.
2 Measured with V
In = VDD or VSS.
3 Measured with V
In = VSS.
4 Measured with V
In = VDD.
5 Power supply must maintain regulation within operating V
DD range during instantaneous and operating
maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may
flow out of VDD and could result in external power supply going out of regulation. Ensure external VDD load will
shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not
consuming power. Examples are: if no system clock is present, or if clock rate is very low (which would reduce
overall power consumption).
6 All functional non-supply pins are internally clamped to V
SS and VDD.
7 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.
8 The RESET pin does not have a clamp diode to V
DD. Do not drive this pin above VDD.
