Working Principles

The 74HC283D/AUJ is an Arithmetic Logic Unit (ALU) integrated circuit that performs 4-bit binary addition with carry. It operates by taking two 4-bit binary numbers (A and B) as inputs along with a carry-in signal (CIN). The ALU then adds the two numbers and produces a 4-bit sum output (S) along with a carry-out signal (COUT).

The ALU uses logic gates and flip-flops internally to perform the addition operation. It follows the rules of binary addition, including handling carry-over from one bit to the next. The carry-out signal can be used to cascade multiple ALUs for larger computations.
