MAX485 RS-485/RS-422 Transceiver IC SMD Package

MAX485 RS-485/RS-422 Transceiver IC SMD Package 

The MAX485 is a low-power RS-485/RS-422 transceiver IC designed for reliable half-duplex serial communication over long distances in noisy environments. It combines a differential line driver and receiver in a single device, enabling robust data transmission using twisted-pair cables.

Operating from a single 5 V supply, the MAX485 is optimized for low power consumption and is well suited for industrial, automation, and embedded communication systems. The surface-mount (SMD) package allows compact PCB layouts and easy integration into modern designs.
