Working Principles

The DM74S283N is an Arithmetic Logic Unit (ALU) that performs arithmetic and logical operations on binary numbers. It operates based on the principles of binary addition and subtraction using logic gates. The ALU takes two 4-bit binary numbers (A and B) as inputs and generates corresponding sum (S) and carry (C) outputs for each bit.

The ALU uses TTL technology, which provides high-speed operation and reliable performance. It utilizes Schottky transistors to achieve fast switching times and low power consumption. The ALU can be cascaded to create larger word sizes by connecting the carry outputs of one ALU to the carry inputs of the next ALU.
