1、Can ts3l110 be replaced by a multiplexer switch with the same bandwidth and on resistance  and  same OISO\same XTALK?

2、What is the key difference between LAN switch and general multiplex switch?

    Zhang,

    1) Yes, as these are just passive FETs, if you can find a switch that exhibits similar characteristics, for sure you can replace it. You would just need to find a 4 channel 2:1 that can handle the signals you're working with. TMUX1574 may be a good bet

    2) Currently you can find general multiplexes that can replace a LAN switch. The 'LAN switch' classification aids in finding a switch that fits specific needs for LAN switching but you can replace it. For example the TMUX1574 has been used and is discussed being replaced in another E2E post:

    LAN switches such as the TS3L110 have some powered sequencing protective features to protect the device from back-powering during powered up/powered down sequencing. Basically it will remain high-Z when you don't want power through. We have a variety of 4channel 2:1 switches that offer this too powered-off protection too. 

    Thanks,
