1. Specification is for parts in the -40 to +85
°
C range. Higher temperature ranges will result in increased
current leakage.
2. See
ATD DC Electrical Characteristics
.
3. It is recommended to tie V

if standby mode is not being used.
4. All functional no-supply pins are internally clamped to V

.
5. 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.
6. Power supply must maintain regulation within operating V
DD
or V

range during instantaneous and operating maximum
current conditions. If positive injection current (V
in

DD
or V
in

DDX
) is greater than I
DD
or I
DDX
, injection current may flow
out of V

/V

and could result in external power supply going out of regulation. Ensure external V

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.
