SN65HVD24DR

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 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. 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.
