The ST3485EBDR with SOP-8 RS-485/RS-422 ICs, manufactured by Youtai and certified to RoHS standards, is an integrated circuit designed for serial data communication applications that are compliant with the RS-485 and/or RS-422 standards. It is housed in an 8-pin Small Outline Package (SOP) and includes two bus transceivers, one transmitter and one receiver, making it suitable for point-to-point serial data transmission over a twisted pair (TP) or shielded twisted pair (STP) network. It is designed for asynchronous data communications over distances of up to 1,200 meters with data rates up to 10 Mbps, and can be automatically switched between the two standards. It also features driver slew rate control, an adjustable slew rate, and fast response time. The IC has been designed with hot-swappable designs, allowing fast, convenient replacement and integration into existing systems. It is ideal for use in office automation, industrial control, instrumentation, and building automation systems.
