SN65LBC172ADWR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the application note SLVA704, which includes guidelines for component placement, trace routing, and grounding to minimize EMI and ensure reliable operation.
  • The termination resistors should be chosen based on the transmission line impedance and the signal frequency. A good starting point is to use 50-ohm resistors for most applications, but the optimal value may vary depending on the specific use case. Consult the application note SLVA705 for more information.
  • The maximum cable length supported by the SN65LBC172ADWR depends on the signal frequency, cable type, and termination. As a general rule, the maximum cable length is around 10-15 meters at 100 Mbps, but it can be longer or shorter depending on the specific application. Consult the application note SLVA706 for more information.
  • To ensure hot-swapping capability, the SN65LBC172ADWR should be used in conjunction with an external TVS (Transient Voltage Suppressor) diode and a 1-kohm resistor in series with the VCC pin. This will protect the device from voltage transients during hot-swapping.
  • The power consumption of the SN65LBC172ADWR in standby mode is typically around 10-20 uA, depending on the specific application and operating conditions. Consult the datasheet for more information.
