LU3X54FT
QUAD-FET for 10Base-T/100Base-TX/FX
Absolute Maximum Ratings
(T
A
= 25
°
C)
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 25. Absolute Maximum Ratings
Table 26. Operating Conditions
* Typical power dissipations are specified at 5.0 V and 25 °C. This is the power dissipated by the LU3X54FT. An additional 0.2 W of power is
required for the external twisted-pair driver termination resistors.
