Description for the SN65HVD1781-Q1

These devices are designed to survive overvoltage faults such as direct shorts to powersupplies, mis-wiring faults, connector failures, cable crushes, and tool mis-applications. They arealso robust to ESD events, with high levels of protection to the human-body-modelspecification.

These devices combine a differential driver and a differential receiver, which operatefrom a single power supply. In the ’HVD1782, the driver differential outputs and the receiverdifferential inputs are connected internally to form a bus port suitable for half-duplex (two-wirebus) communication. This port features a wide common-mode voltage range, making the devicessuitable for multipoint applications over long cable runs. These devices are characterized from–40°C to 125°C. These devices are pin-compatible with the industry-standard SN75176 transceiver,making them drop-in upgrades in most systems.

These devices are fully compliant with ANSI TIA/EIA 485-A with a 5-V supply and canoperate with a 3.3-V supply with reduced driver output voltage for low-power applications. Forapplications where operation is required over an extended common-mode voltage range, see theSN65HVD1785 (SLLS872) data sheet.
