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) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All
voltages are measured with respect to the ground pin, unless otherwise specified.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The maximum power dissipation must be de-rated at elevated temperatures and is dictated by T
JMAX
, θ
JC
, and the ambient temperature
T
A
. The maximum allowable power dissipation is P
DMAX
= (T
JMAX
– T
A
) / θ
JA
or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LMV1089, T
JMAX
= 150°C and the typical θJA for this DSBGA package is 70°C/W and for the LLP package
θ
JA
is 64°C/W Refer to the Thermal Considerations section for more information.
