Working Principles

The MAX208IDWRG4 is a transceiver that facilitates bidirectional communication between devices using the RS-485 and RS-422 protocols. It operates by converting the differential voltage levels of the A and B inputs into corresponding differential outputs Y and Z. The DE (Driver Enable) and /RE (Receiver Enable) pins control the direction of data flow. When DE is high and /RE is low, the device is in transmit mode, and when DE is low and /RE is high, it is in receive mode.
