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) All voltages are measured with respect to the GND pin (pin 3), unless otherwise specified.
(2) 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 specify specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication
of device performance.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) Human body model, 100 pF discharged through a 1.5 kΩ resistor.
(5) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
, θ
JA
, and the ambient temperature
T
A
. The maximum allowable power dissipation is P
D
= (T

)/θ
JA
or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LM1971N and LM1971M, T
JMAX
= +150°C, and the typical junction-to-ambient thermal resistance, θ
JA
, when
board mounted is 102° C/W and 167° C/W, respectively.
