SN65HVD1781-Q1 具有故障保护功能的汽车类 70V RS-485 收发器
These devices are designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes, and tool mis-applications. They are also robust to ESD events, with high levels of protection to the human-body-model specification.
These devices combine a differential driver and a differential receiver, which operate from a single power supply. In the 'HVD1782, 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. This port features a wide common-mode voltage range, making the devices suitable for multipoint applications over long cable runs
