Working Principles

The MAX13486EESA+T is designed to facilitate communication between devices using the RS-485/RS-422 protocol. It acts as a transceiver, converting electrical signals between the driver and receiver sides of the communication link.

When transmitting data, the driver inputs (A and B) receive digital signals and convert them into differential voltage outputs (Y and Z). These outputs are then transmitted over the communication line.

On the receiving side, the transceiver receives differential voltage inputs (Y and Z) and converts them into digital signals at the receiver outputs (A and B).

The transceiver also features automatic switching between half-duplex and full-duplex modes. This allows bidirectional communication on a single communication line, simplifying system design.
