I just saw this question where the OP tagged the question as and .

Looking at the info for , there's no information whatsoever.

With , this is different.

Is there a reason why we need both of these tags if one is simply a shorthanded writing expression of the other? Both tags do receive a fair amount of utilization.

  • \$\begingroup\$ What is a "multiplexer" anyway? Is it a 74HC digital mux, a RF multiplexer, an analog switch, something else? Seems fairly ambiguous to me. If you just say "mux" though, I will assume some 74HC standard digital IC. \$\endgroup\$

    \$\begingroup\$ @Lundin Well my point was these two tags are homogeneous. You can use these two expressions interchangeably (even for an RF multiplexer, you can say "mux" as well). I believe the action of implementing a multiplexer is either called muxing or multiplexing. Overall, these two expressions can be used at the same time. I don't think the community will delete one or the other but rather combine both of them into a single tag. So when a user tags a question as "mux", "multiplexer" will also show up under the same option. \$\endgroup\$

  • \$\begingroup\$ @Lundin. I assume nothing by the term 'mux'. Sure there is analog and digital, but there is a huge gap in speed between a 74HCxx series and MC100EPxx ECL series, some of which work to 3 GHZ. \$\endgroup\$

  • \$\begingroup\$ Isn't a mux and a multiplexer the same thing? \$\endgroup\$

There doesn't seem to be any point having both of them.

I've proposed the tag synonym on the multiplexer page to have mapped to as they are basically common terms for the same thing.

    \$\begingroup\$ Muxing is also a synonym :) Unfortunately I don't have enough "rep" to vote on this. \$\endgroup\$

  • \$\begingroup\$ @KingDuken Mux is now a synonym. I've not proposed muxing for now as there are no questions tagged with it. If that changes later, it can always be proposed. \$\endgroup\$ Nov 13, 2018 at 12:49
