SN65HVD1040DRG4 Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD1040DRG4?
  The maximum cable length supported by the SN65HVD1040DRG4 is approximately 100 meters, depending on the cable quality and the baud rate.
• How do I ensure signal integrity and minimize electromagnetic interference (EMI) when using the SN65HVD1040DRG4?
  To ensure signal integrity and minimize EMI, use twisted-pair cables, keep the transmitter and receiver close to each other, use shielding, and follow proper PCB layout and grounding techniques.
• What is the recommended termination scheme for the SN65HVD1040DRG4?
  The recommended termination scheme for the SN65HVD1040DRG4 is a 120-ohm differential termination resistor at the receiving end, and a 1-kohm pull-up resistor to VCC at the transmitting end.
• Can I use the SN65HVD1040DRG4 for applications other than RS-485?
  Yes, the SN65HVD1040DRG4 can be used for other applications that require a half-duplex transceiver, such as RS-422 or other proprietary protocols.
• How do I handle hot-swapping or hot-plugging with the SN65HVD1040DRG4?
  To handle hot-swapping or hot-plugging, use a external switch or a dedicated hot-swap controller to ensure that the bus is properly terminated and the device is properly powered down before removal.
