Description
General part information
SN65HVD20 Series
The transceivers in the SN65HVD2x 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 designed 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.
These devices combine a 3-state differential driver and a differential receiver that operate 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.
