I have a DSPT dual single pole double throw analog switch (Dual channel 2:1 mux/demux). Now I have some questions regarding analog switches?
- How do these differ from digital mux which I am faimilar with (which is basically a selector between multiple inputs based on some select signals)? Whats strange is the schematic of the circuit uses digital signals TTL as inputs/outputs? I read some where that some analog switches allow digital signals?
- The part says its a switch (mux/demux). Does that mean the inputs and outputs can be swapped. Basically is it like a physical connection between 2 set of pins based on a select line. Because from my understanding thats what a switch is? more over it says its mux/demux?
I hope someone can clarify this.
