Maximum Ratings
Table 20
lists thermal resistance values.
NOTE
The use of this device in one- or two-layer board designs is not recommended due to the
limited thermal conductance provided by those boards.

Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum
Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress
beyond those listed may affect device reliability or cause permanent damage to the device.
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 (e.g., either V
SS
or V
DD
).
Input must be current limited to the I
DD
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.
All functional non-supply pins are internally clamped to V
SS
and V
DD
.
The power supply must maintain regulation within operating V
DD
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. Insure 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 (ex; no clock). The power supply
must maintain regulation within operating V
DD
range during instantaneous and operating maximum
current conditions.
