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 are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.

(1) Measurements are performed on a 4 layer JEDEC board with 10 vias provided under the exposed pad. See JESD51-1 to JESD51-11.
The value of θ_JA is specifically dependent on the PCB trace area, trace material and the number of layers and thermal vias.

Electrical Characteristics (LM3464/LM3464A)
Specification with standard type are for T_A = T_J = +25°C only; limits in boldface type apply over the full Operating Junction
Temperature (T_J) range. Minimum and Maximum are specified through test, design or statistical correlation. Typical values
represent the most likely parametric norm at T_J = +25°C, and are provided for reference purposes only. Unless otherwise
stated the following conditions apply: V_IN = 48V.
