SN65HVD78DR Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65HVD78DR is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 100 meters at 9600 bps and 10 meters at 1 Mbps.
  • The SN65HVD78DR can be configured for half-duplex or full-duplex operation by connecting the RTS (Request to Send) pin to the CTS (Clear to Send) pin for half-duplex operation, or by connecting the RTS pin to a microcontroller or other control logic for full-duplex operation.
  • The SN65HVD78DR supports data rates up to 1 Mbps.
  • Yes, the SN65HVD78DR is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard.
  • The SN65HVD78DR has built-in ESD protection, but additional protection measures such as TVS diodes or surge protectors can be used to further protect the device from transient events.
