德州仪器的扩展共模 RS-485 收发器 SN65HVD23Dr
Extended Common Mode RS-485 Transceivers
收发器IC SN65HVD23的说明
The transceivers in the HVD2x family offer performance far 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.
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.
