I have used DG333, 405, 408/9, 412, 418/9 - hopefully I haven't overlooked anything obvious in those sorts of ranges.<br>
The little DG419 is quite useful and compact.<br>

Why not use individual FETs? That’s what the mux chips are made from.<br>
<br>
You might need a pair in parallel, or other tricks, but it should be possible to create a 3-way, 2-bit switch from discrete parts.<br>
<br>
By the way, the DG series also has two-way switches. Look at the DG333 or the DG401, DG403, DG405.<br>

I've used & liked a range of different DG4xx chips, but was wondering if anyone can think of a small/low-priced analogue switch/multiplexer - and +/-15V operation & pref in SMD.<br>
<br>
The main thing is implementing remote/panel switching of signals - typically from a spdt centre-off switch, so 3 way // 2 bit. Something in S08 & cheap would be ideal!<br>
<br>
It always seems a waste to use a big 8 way / 3bit mux for such things..<br>
<br>
Thanks for any ideas, Tom<br>
