How will you form an 8 bit adder using 2 four bit adder IC's 7483?
Ans:
4 bit adder IC is IC 7483. This has two four bit data inputs and output carry, 4 bit data output carry. All two IC's must be linked in cascade, the first IC will add lower order bits and this generates sum and carry. Its carry must be the input of second IC, and the inputs of second IC will be the higher order bits of number A and B.
