SN65HVD1782DR

Description
The SN65HVD178x 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.
The devices are also robust to ESD events with high levels of protection to the human-body-model specification.
The SN65HVD178x devices combine a differential driver and a differential receiver, which operate from a single power supply. In the SN65HVD1782, the driver differential outputs and the receiver differential inputs are connected internally to form a bus portsuitable for half-duplex (two-wire bus) communication. This port features a wide commonmode voltage range, making the devices suitable for multipoint applications over long cable runs.
These devices are characterized from –40°C to 125°C.
These devices are pin compatible with the industrystandard 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 can operate with a 3.3-V supply with reduced driver output voltage for lowpower applications.
