Working Principles

The SN74F283DR is an Arithmetic Logic Unit (ALU) that performs arithmetic and logic operations in digital systems. It operates on binary inputs A and B, producing a sum output and a carry-out signal. The carry-in input allows for cascading multiple ALUs to perform operations on larger word sizes.

The ALU uses TTL logic, which provides high-speed operation but may consume more power compared to newer logic families. The propagation delay of 9 ns (typical) determines the time required for the output to stabilize after the inputs change.
