Working Principles

MAX488CUA+T is designed to facilitate bidirectional data communication over long distances using the RS-485/RS-422 standard. It features a single driver and receiver, enabling half-duplex operation. The DE (Driver Enable) and RE (Receiver Enable) pins control the direction of data flow. When DE is high and RE is low, the driver is enabled and transmits data from the A and B inputs. Conversely, when DE is low and RE is high, the receiver is enabled and receives data on the A and B outputs.
