Working Principles

The MAX3485AEASA+T is a transceiver IC designed for RS-485/RS-422 communication. It utilizes differential signaling to transmit data over long distances. The DE (Driver Output Enable) and RE (Receiver Output Enable) pins control the direction of data flow. When DE is high and RE is low, the device operates in transmit mode, allowing data to be sent from the A and B inputs. In receive mode, with DE low and RE high, the device receives data on the A and B outputs.
