Description
The transceivers in the SN65HVD20D family offer performance far exceeding typical RS-485 devices. In addition to meeting all requirements of the TIA/EIA‑485-A standard. The SN65HVD2x family operates over an extended range of common-mode voltages 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. These devices are 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.
