SN65HVD251D datasheet by Texas Instruments

SN65HVD251D Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD251D?
  The maximum cable length supported by the SN65HVD251D is dependent on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths of up to 100 meters at a data rate of 100 Mbps.
• How does the SN65HVD251D handle common-mode voltage?
  The SN65HVD251D has a common-mode voltage range of -7V to 12V, which allows it to operate in noisy environments with high levels of electromagnetic interference (EMI). The device also has a built-in common-mode filter to help reject common-mode noise.
• What is the power consumption of the SN65HVD251D?
  The power consumption of the SN65HVD251D is typically around 150 mW at a supply voltage of 5V and a data rate of 100 Mbps. However, the actual power consumption may vary depending on the specific application and operating conditions.
• Is the SN65HVD251D compatible with other RS-485 transceivers?
  Yes, the SN65HVD251D is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard. However, it's always recommended to verify compatibility with specific devices and systems before deployment.
• How does the SN65HVD251D handle bus contention?
  The SN65HVD251D has a built-in bus contention resolution mechanism that allows it to handle multiple devices transmitting simultaneously on the bus. The device uses a non-destructive bitwise OR operation to resolve bus contention and ensure reliable data transmission.
