SN65HVD20 - Extended Common-Mode RS-485 Transceivers

General 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.

Key Features

  • 1 Common-Mode Voltage Range (.
  • 20 V to 25 V) More Than Doubles TIA/EIA-485 Requirement.
  • Receiver Equalization Extends Cable Length, Signaling Rate (SN65HVD2[3,4]).
  • Reduced Unit-Load for up to 256 Nodes.
  • Bus I/O Protection to Over 16-kV HBM.
  • Failsafe Receiver for Open-Circuit, Short-Circuit, and Idle-Bus Conditions.
  • Low Standby Supply Current 1 µA (Maximum).
  • More Than 100 mV Receiver Hysteresis 2.
