Texas Instruments SN65HVD1780DR
The SN65HVD178x devices are designed to survive overvoltage faults such as direct shortsto power supplies, mis-wiring faults, connector failures, cable crushes, and tool mis-applications.The devices are also robust to ESD events with high levels of protection to the human-body-modelspecification.
The SN65HVD178x devices combine a differential driver and a differential receiver, whichoperate from a single power supply. In the SN65HVD1782, the driver differential outputs and thereceiver 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 thedevices suitable for multipoint applications over long cable runs. These devices are characterizedfrom –40°C to 125°C. These devices are pin-compatible with the industry-standard SN75176transceiver,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.
