Function "4: bOut = f (Truth table)"
When the function "4: bOut = f (truth table)" is selected in
C00822 , the output value bOut depends
on the truth table parameterised in C00823/1...8 .
The following table shows which setting may be required in C00823/1...8 to realise the logic
operations NAND, NOR, XOR and XNOR:
C00823/1...8 Truth table for function "4: bOut = f
(truth table)"
• Each of the eight possible input
combinations can be assigned to
the output value FALSE or TRUE.
• For an application example see
the following section.
0 FALSE
1 TRUE
