[DMUX8_BO] Demultiplexer 1 of 8 boolean values

Function block DMUX8_BO switches the Boolean input to one of the 8 outputs in dependence of a selector.

DMUX8_BO switches the Boolean input to one of the 8 outputs in dependence of a selector.

DMUX8_BO switches the input [In] to the output [Out0] ... [Out7] defined by selector [K]. All other outputs are set to default value [DefVal].

If the value of input [K] is smaller than 0 or greater than 7, all outputs [Out0]...[Out7] are set to [DefVal].

Cascading

DMUX8_BO can be cascaded, e.g. to demultiplex 16 outputs. Instead, multiple DMUX8_BO are switched in parallel with the same input value [In]. Selector [K] is adapted by subtraction.

Selector K	Output
Selector K	Out0	Out1	Out2	Out3	Out4	Out5	Out6	Out7	ReqK
K < 0	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	-1
K = 0	In	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	-1
K = 1	DefVal	In	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	-1
K = 2	DefVal	DefVal	In	DefVal	DefVal	DefVal	DefVal	DefVal	-1
K = 3	DefVal	DefVal	DefVal	In	DefVal	DefVal	DefVal	DefVal	-1
K = 4	DefVal	DefVal	DefVal	DefVal	In	DefVal	DefVal	DefVal	-1
K = 5	DefVal	DefVal	DefVal	DefVal	DefVal	In	DefVal	DefVal	-1
K = 6	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	In	DefVal	-1
K = 7	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	In	-1
K > 7	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	DefVal	K - 8

Pins

Input	Description	Data type	Default value Value range
K	Selector	Integer	0
In	Input	Boolean	0
In	0 - Input disabled. 1 - Input enabled.
DefVal	Default value	Boolean	0
DefVal	0 - No 1 - Yes

Output	Description	Data type	Default value Value range
Out0…Out7	Output 0…Output 7	Boolean	0
ReqK	Request selector	Integer	0

Application

DMUX8_BO normally is used to reset signals interconnected via a multiplexer.

For example, a communication path featuring an integer and Boolean pin only can be used to transmit up to 8 different values in sequence.
