These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not guarantee specific performance limits.

Refer to RETS108X for LM108 military specifications and RETs 108AX for LM108A military specifications.
(3)
The maximum junction temperature of the LM108 is 150°C, for the LM208, 100°C and for the LM308, 85°C. For operating at elevated
temperatures, devices in the H08 package must be derated based on a thermal resistance of 160°C/W, junction to ambient, or 20°C/W,
junction to case. The thermal resistance of the dual-in-line package is 100°C/W, junction to ambient.
(4)
The inputs are shunted with back-to-back diodes for overvoltage protection. Therefore, excessive current will flow if a differential input
voltage in excess of 1V is applied between the inputs unless some limiting resistance is used.
(5)
For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
