Working Principles

The MAX4815ETE+T is designed to facilitate reliable data transmission over long distances using the RS-485/RS-422 communication standards. It incorporates a driver and a receiver to enable bidirectional communication. The driver converts the logic-level signals into differential voltage signals suitable for long-distance transmission, while the receiver converts the received differential signals back into logic-level signals.
