This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltage values are with respect to network ground terminal.
(3)
The human body model is a 100-pF capacitor discharged through a 1.5-k
resistor into each pin. The machine model is a 200-pF
capacitor discharged directly into each pin.

Maximum power dissipation is a function of TJ(max), qJA and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/ qJA.
(2)
This thermal data measured with high-K board (4 layers according to JESD51-7 JEDEC Standard).
