RS−485 Devices RS-485

The SN65HVD21M offers performance exceeding typical RS−485 devices. In addition to meeting all requirements of the TIA/EIA−485−A standard, the HVD2x family operates over an extended range of common-mode voltage, and has features such as high ESD protection, wide receiver hysteresis, and failsafe operation. This family of devices is ideally suited for long-cable networks, and other applications where the environment is too harsh for ordinary transceivers. The SN65HVD21M is designed for bidirectional data transmission on multipoint twisted-pair cables. Example applications are digital Motor Controllers remote Sensors and terminals, industrial process control, security stations, and environmental control systems. The SN65HVD21M combines a 3-state differential driver and a differential receiver, which operates from a single 5-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a differential bus port that offers minimum loading to the bus. This port features an extended common-mode voltage range making the device suitable for multipoint applications over long cable runs. The SN65HVD21M allows up to 256 connected nodes at moderate data rates (up to 5 Mbps). The driver output slew rate is controlled to provide reliable switching with shaped transitions which reduce high-frequency noise emissions. By Texas Instruments
