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 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 specified for parameters where no limit is given, however, the typical value is a good indication of device
performance.
(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 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_DMAX = (T_JMAX − T_A)/θ_JA or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LM4880, T_JMAX = 150°C, and the typical junction-to-ambient thermal resistance is 170°C/W for package
D0008A and 107°C/W for package P0008E.
(4) Human body model, 100 pF discharged through a 1.5 kΩ resistor.
(5) Machine model, 220 pF–240 pF discharged through all pins.
