The SN65HVD1785D is a RS-485 Fault-protected Transceiver with extended common-mode range. This device is designed to survive over-voltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes and tool mis-applications. It is also robust to ESD events, with high levels of protection to human-body model specifications. This device combines a differential driver and a differential receiver, which operate from a single power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. These ports feature a wide common-mode voltage range, making the device suitable for multipoint applications over long cable runs.
