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.

(1) Refer to RETS185H-2.5 for military specifications.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4) For elevated temperature operation, T_{J MAX} is:
LM185-N: 150°C
LM285-N: 125°C
LM385-N: 100°C
See THERMAL CHARACTERISTICS.
(5) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
