DescriptionThe transceivers in the SN65HVD2x family offer
performancefar exceeding typical RS-485 devices.In
addition to meeting all requirements of the
TIA/EIA‑485-A standard. The SN65HVD2x family
operates over an extended rangeof common-mode
voltages and has features such as high ESD
protection, wide receiver hysteresis, and failsafe
operation. This familyof devicesis ideally suited for
long-cable networks and other applications where the
environmentis too harshfor ordinary transceivers.
These devices are designed for bidirectional data
