recommends the use of θ
temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures
can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature
specification can be verified by physical measurement in the customer’s system using the Ψ
dissipation, and the method described in EIA/JESD Standard 51-2.

Thermal resistance between the die and the printed circuit board in conformance with JEDEC JESD51-8. Board
temperature is measured on the top surface of the board near the package.

Thermal Characteristics
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., V
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.
All functional non-supply pins are internally clamped to V
Power supply must maintain regulation within operating O V
operating maximum current conditions. If positive injection current (V
injection current may flow out of O V
regulation. Ensure the external O V
is the greatest risk when the MCU is not consuming power (ex; no clock).Power supply must maintain
regulation within operating V
