Note 1
The maximum junction temperature of the LM321A is 85 C For operating at elevated temperature devices in the H08 package must be derated based on
a thermal resistance of 150 C W junction to ambient or 18 C W junction to case
Note 2
The inputs are shunted with back-to-back diodes in series with a 500X resistor for overvoltage protection Therefore excessive current will flow if a
differential input voltage in excess of 1V is applied between the inputs
Note 3
For supply voltages less than
g
15V the absolute maximum input voltage is equal to the supply voltage

These specifications apply for
