Electrical Characteristics
4 _{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.
5 _{Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current}
conditions. If the 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 that 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 _{Maximum is highest voltage that POR is guaranteed.}
