SLLS552F – DECEMBER 2002 – REVISED NOVEMBER 2016 SN65HVD2x Extended Common-Mode RS-485 Transceivers
1 Features 3 Description The transceivers in the SN65HVD2x family offer
performance far 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 range of common-mode
voltages and has features such as high ESD
protection, wide receiver hysteresis, and failsafe
operation. This family of devices is ideally suited for
long-cable networks and other applications where the
environment is too harsh for ordinary transceivers. 1 Common-Mode Voltage Range (–20 V to 25 V)
