Working Principles

The CD74ACT283M is an Arithmetic Logic Unit (ALU) integrated circuit that performs binary addition of two 4-bit numbers. It utilizes advanced CMOS technology, which provides high-speed operation while consuming low power.

The ALU takes two 4-bit inputs (A and B) and generates a 4-bit sum output (S) along with a carry output (Cout). The carry input (Cn) allows cascading multiple ICs for larger bit-width addition.

During operation, the ALU adds corresponding bits of A and B, taking into account the carry input. The sum output represents the result of the addition, while the carry output indicates whether there was a carry-over from the most significant bit.
