Working Principles

The SN74LS283DR is an Arithmetic Logic Unit (ALU) integrated circuit that performs binary addition with carry. It operates on four input bits (A0-A3 and B0-B3) and generates four sum outputs (S0-S3) along with a carry out (COUT). The ALU uses LS-TTL logic family, which provides high-speed operation and low-power consumption.

The addition process involves adding the corresponding bits of A and B inputs, along with any carry-in from a previous stage. The sum outputs are generated based on the result of the addition, while the carry out indicates whether an overflow occurred during the addition.
