SN65HVD21M-EP 增强型产品扩展共模 Rs-485 收发器

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
