The SN65HVD20D is an extended common-mode RS-485 Transceiver offers 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 device is ideally suited for long-cable networks and other applications where the environment is too harsh for ordinary transceivers. This device is designed for bidirectional data transmission on multipoint twisted-pair cables.
