The AM26LS32ACDR IC functions as a line driver that provides four differential output pairs. These outputs are designed to drive data signals over a balanced differential transmission line, which is often used for long-distance communication or high-speed digital signals. The IC takes inputs in pairs (A1, B1 for the first pair, A2, B2 for the second pair, and so on) and produces corresponding differential outputs (Y1, Y1' for the first pair, Y2, Y2' for the second, etc.).
It operates typically with a 5V power supply and ensures that the outputs conform to the EIA-485 standard, a commonly used standard for balanced transmission.
