This VI simulates an IC 74LS190.
Changing the 4 addresses in Input, you will have in Output, in corrispondence with the binary number selected, the decimal equivalent, that is shown on an LED Display 7SEGMENTS.
B0 as the lowest Input value, follows B1, B2 and B3.
A as the lowest Output value, follows B, C... G.
Example:
With the binary combination 0101 you will have the number 6 (Decimal equivalent) shown on a LED Display 7SEG.
Follows the truth table:
