SN65HVD251DR datasheet by Texas Instruments

SN65HVD251DR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD251DR?
  The maximum cable length supported by the SN65HVD251DR 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 1 Mbps.
• How does the SN65HVD251DR handle common-mode voltage?
  The SN65HVD251DR 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 high common-mode rejection ratio (CMRR) of 80 dB, which helps to reject common-mode noise.
• What is the maximum data rate supported by the SN65HVD251DR?
  The SN65HVD251DR supports data rates of up to 1 Mbps, making it suitable for a wide range of industrial and automotive applications.
• Is the SN65HVD251DR compatible with other RS-485 transceivers?
  Yes, the SN65HVD251DR 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 integration.
• How does the SN65HVD251DR handle bus contention?
  The SN65HVD251DR has a built-in bus contention resolution mechanism that allows multiple devices to share the same bus without data corruption. The device also has a high impedance when not transmitting, which helps to prevent bus contention.
