1 _{Typical values are based on characterization data at 25°C unless otherwise stated.}
2 _{Measured with VIn = VDD or VSS.}
3 _{Measured with VIn = VSS.}
4 _{Measured with VIn = VDD.}
5 _{Power supply must maintain regulation within operating VDD range during instantaneous and operating}
maximum current conditions. If positive injection current (V_In > V_DD) is greater than I_DD, the injection current
may flow out of V_DD and could result in external power supply going out of regulation. Ensure external V_DD
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 VSS 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.
