,
can be calculated using the following equation:
j
= P*

a
Where,
P = Power
Ja
= Junction to ambient temperature (

)
a
= Ambient temperature (70 °C)
The case temperature
c
, can be calculated using the following equation:
c
= P*
Ca
+
a
where,
P = Power
Ca
= Case to ambient temperature
a
= Ambient temperature (70 °C)
Note
15. Do not power I/O with chip power off.
