SN65HVD20D datasheet



The transceivers in the SN65HVD20D 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. These devices are designed for bidirectional data transmission on multipoint twisted-pair cables. Example applications are digital motor controllers, remote sensors and terminals, industrial process control, security stations, and environmental control systems.




• 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
