SN65HVD78DRBR Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65HVD78DRBR 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 1 Mbps and 40 meters at 10 Mbps.
  • To ensure EMC with the SN65HVD78DRBR, follow proper PCB layout and design guidelines, use a common-mode choke or ferrite bead on the bus, and ensure proper shielding and grounding of the cable and connectors.
  • The recommended termination scheme for the SN65HVD78DRBR is a 120-ohm differential termination resistor at the receiving end of the bus, and a 1-kohm to 4.7-kohm pull-up resistor to VCC at the transmitting end.
  • To handle hot-swapping with the SN65HVD78DRBR, use a hot-swap controller or a power switch with overcurrent protection, and ensure that the device is powered down before disconnecting or connecting the bus.
  • The maximum operating temperature range for the SN65HVD78DRBR is -40°C to 125°C, but the device can be operated at a reduced temperature range of -20°C to 85°C for most applications.
