Working Principles

The CD74HCT283M is an Arithmetic Logic Unit (ALU) integrated circuit that performs 4-bit binary addition and subtraction operations. It utilizes high-speed CMOS technology, providing fast and efficient calculations. The ALU takes two 4-bit inputs (A and B) and generates a 4-bit sum output (S) along with carry-out (COUT), less than (LT), equal to (EQ), and greater than (GT) outputs.

The ALU operates based on the principles of binary arithmetic. It uses logic gates and flip-flops to perform addition and subtraction operations. The carry-in (CIN) input allows for cascading multiple ALUs to perform calculations on larger word sizes.
