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 ensure specific performance limits.

(2)

A military RETS specification is available upon request. At the time of printing, the LM140LA-5.0, -12, and -15 RETS specifications

complied with the Min and Max limits in this table. The LM140LAH-5.0, LM140LAH-12, and LM140LAH-15 may also be procured as

Standard Military Drawings.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

Thermal resistance of NDT-package is typically 26°C/W

θjC, 250°C/W θjA still air, and 94°C/W θjA 400 lf/min of air. For the LP-package is

60°C/W

θjC, 232°C/W θjA still air, and 88°C/W θjA at 400 lf/min of air. The maximum junction temperature shall not exceed 125°C on

electrical parameters.
