LU3X34FTR
Quad 3 V 10/100 Ethernet Transceiver TX/FX
dc and ac Specifications
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Table 32. Absolute Maximum Ratings
Table 33. Operating Conditions
* Typical power dissipations are specified at 3.3 V and 25 °C. This is the power dissipated by the LU3X34FTR.
