SLVS590A–JULY 2005–REVISED AUGUST 2005
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.

(1) 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) IRTN = 0 for VRTN > 80 V. Maximum IRTN = 500 mA at 80 V.
(3) Do not apply external voltage sources to CLASS, DET, GATE, FREQ, VBIAS, and TMR.
(4) Surges applied to RJ-45 of Figure 40 between pins of RJ-45, and between pins and output voltage rails per EN61000-4-2, 1999 with no
