The WS3081 manufactured by Guobo Electronics is a SOP-8 RS-485/RS-422 IC that is RoHS compliant. This IC implements the RS-485 and RS-422 protocols in a single IC package, allowing for the harvesting and transfer of data over a single two-wire differential serial bus. It is designed for interfacing in multi-drop networks, allowing for up to 128 nodes on a single chain. This IC is ideally suited for distributed control systems, industrial automation, and sensor/actuator networks. Furthermore, it utilizes low-power CMOS technology, further reducing power consumption compared to similar products on the market.
