Description

IC 7483 = Binary Adder. IC 7486 = EX-OR gate. "A" & "B"series & Cin are in input section. "S" series & Cout are in ouput section. Ao=12, A1=13, A2=14,A3=15, Cin=10. Bo=0, B1=1, B2=2, B3=3. So=0, S1=1, S2=2, S3=3, Cout=10. After connecting, in A & B series input binary code as 1111 & Cin as 0 and 1 each time & the S series will output by glowing red light with binary output as 1110(cin=0) & 0000(Cin=1).
