If you are not using negative numbers i.e two complement, then FFFF hex (1111111111111111 )is the largest integer ( =65,535 in decimal).

If you are using 2's complement then the largest number is 7FFF hex, (01111111111111111) which is 32,767

That depends on how the outputs are related to numbers. Is it sign+value? 1's complement? 2's complement? All positive? Something else?
