Update:
I do need all 3 wires to be MUXed and all 3 wires needs to go through the same chip - that is the price I have to pay for 3-wire PT100.
NX3L4053PW - 3.3V , Ron 1ohm - one for each two PT100.
TS3A44159 - 3.3V, Ron 0.45ohm - NO, it does not have EN pin!
TMUX1574- 5V, Ron 2ohm - one for each two PT100.
TMUX1511 - 5V, Ron 2ohm - one for each PT100.
Any other suggestions for 3/4 pole switch with low Ron, preferably double throw (so I can hook two PT100) and with EN pin (so I can disconnect both)?
