Working Principles

The SN74S283N is a 4-bit binary full adder that performs addition of two 4-bit binary numbers (A and B) along with a carry-in (CIN) input. It utilizes logic gates and flip-flops internally to generate the sum (S) and carry-out (COUT) outputs. The carry-in input is used to handle carry-over from previous stages in multi-bit addition operations.
