Hello there.
I'm relatively new to (digital) circuits, so I search an IC with the following truth table best in the 74xx line:
Where 1 coult be 0 and vice versa, x = don't cares, Z = high impedance and a != b != c != d.
I'll create a priority system. When the first component "activate" the line, the circuit should do something, no matter the other components. When the second compontent activate the line and the first don't do it, the circuit should do something other, no matter component 2 and 3 do it.
I won't build this using simple logic gates, because this get big.
Thank you

Code:
In In In In Out
0 0 0 0 x (maybe Z)
1 x x x a
0 1 x x b
0 0 1 x c
0 0 0 1 d
