Demultiplexer
Verhalten
Copies the input on the west edge onto exactly one of the outputs on
the east edge; which of these outputs is specified via the
current value received through the input on the south edge.
I find it useful to think of a demultiplexer as analogous to a railroad
switch, controlled by the select input.
(Incidentally, some authorities spell this
demultiplexor,
but demultiplexer is the predominant
spelling.)
Pins (wenn das Bauelement nach Osten zeigt)
- West edge (input, bit width matches Data Bits attribute)
- The value to be routed to one of the outputs on the east edge.
- East edge, variable number (outputs, bit width matches Data Bits
attribute)
- The outputs are numbered starting with 0 on the north. An output
will match the west input if its number matches the value currently
received through the select input on the south; otherwise, its value
will be either all-zeroes or all-floating, depending on the value of
the Three-State? attribute.
If the select input contains any unspecified bits, then all outputs are
floating.
- South edge (input, bit width matches Select Bits attribute)
- Select input: The value of this input determines to which output on
the east edge to route the value received on the west edge.
Attribute
When the component is selected or being added,
the digits '1' through '4' alter its Select Bits
attribute,
Alt-0 through Alt-9 alter its Data Bits
attribute,
and the arrow keys alter its Facing
attribute.
- Ausrichtung
- The direction of the component (specifying which side has the outputs).
- Auswahlleitungen
- The bit width of the component's select input on its south edge.
The number of outputs for the demultiplexer will be
2selectBits.
- Data Bits
- The bit width of the data being routed through the demultiplexer.
- Three-state?
- Specifies whether the unselected outputs should be floating (Yes) or
zero (No).
