The SN65HVD1781D is a fault-protected RS-485 Transceiver, 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. This device combines a differential driver and a differential receiver, which operate from a single power supply. In the SN65HVD1781D, 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. These devices are characterized from -40 to 125°C. This device is pin-compatible with the industry-standard SN75176 transceiver, making them drop-in upgrades in most systems.
