Note 1:
Absolute maximum ratings are not necessarily concurrent, and care must be taken not to exceed the maximum junction temperature of the LM143 (150
§
C)
or the LM343 (100
§
C). For operating at elevated temperatures, devices in the H08 package must be derated based on a thermal resistance of 155

C/W, junction to
ambient, or 20
§
C/W, junction to case.
Note 2:
For supply voltage less than
g
40V for the LM143 and less than
