Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
DEC
SymbolsBinary decoder / demultiplexer
Uses binary selection and enable conditions to activate the documented selected output.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
A decoder and a demultiplexer can share a device implementation; this record combines those uses rather than counting the same hardware twice.
MUX
SymbolsDigital multiplexer
Selects one of several digital inputs for the documented output according to its selection controls.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
A digital multiplexer processes logic levels; an analogue multiplexer passes a continuous signal within its electrical limits.
