8-Pin SO (derate 5.88mW/°C above +70°C)...............471mW
8-Pin PDIP (derate 6.9mW/°C above +70°C)...............552mW
8-Pin CERDIP (derate 8.0mW/°C above +70°C).........640mW
Note 1:
Maxim recommends limiting the input current to 100μA to avoid latchup problems. A value of 1mA is typically safe; however,
this is not guaranteed.

= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
