SN75161BDW datasheet by Texas Instruments

SN75161BDW Frequently Asked Questions (FAQs)

• What is the maximum data rate that the SN75161BDW can support?
  The SN75161BDW can support data rates up to 100 Mbps.
• Is the SN75161BDW compatible with other RS-485 transceivers?
  Yes, the SN75161BDW is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard.
• How do I ensure that the SN75161BDW is properly terminated?
  To ensure proper termination, a 120-ohm termination resistor should be connected between the differential outputs (Y and Z) and a common-mode termination voltage (typically VCC or GND) at the receiving end of the bus.
• What is the maximum cable length that can be used with the SN75161BDW?
  The maximum cable length depends on the data rate and cable characteristics, but a general guideline is to limit the cable length to 4000 feet (1219 meters) at a data rate of 100 kbps.
• How do I handle bus contention and fault tolerance with the SN75161BDW?
  To handle bus contention, use a collision detection mechanism, such as a non-return-to-zero (NRZ) encoding scheme. For fault tolerance, implement a fault detection and correction mechanism, such as a watchdog timer and error-checking protocols.
