The data inputs of upper 8x1 multiplexer are i 15 to i 8 and the data inputs of lower 8x1 multiplexer are i 7 to i 0. In the 8 1 mux we need eight and gates one or gate and three not gates. Full adder circuit working and truth table.
The following is my interpretation of the data sheet s truth table with the pin names slightly modified to match the chip diagram shown above.
