DS14C89AN/NOPB datasheet by Texas Instruments

DS14C89AN/NOPB Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the DS14C89AN/NOPB?
  The recommended operating temperature range for the DS14C89AN/NOPB is -40°C to 85°C.
• How do I ensure reliable data transmission over long distances using the DS14C89AN/NOPB?
  To ensure reliable data transmission over long distances, use twisted-pair or shielded cables, and consider using repeaters or line drivers to boost the signal. Additionally, ensure that the transmission line is properly terminated to minimize reflections and signal degradation.
• Can I use the DS14C89AN/NOPB in a multi-point or multi-drop configuration?
  Yes, the DS14C89AN/NOPB can be used in a multi-point or multi-drop configuration. However, it's essential to ensure that the total capacitance of the bus does not exceed the recommended maximum capacitance of 400 pF.
• How do I handle common-mode voltage transients and noise in my RS-485 system using the DS14C89AN/NOPB?
  To handle common-mode voltage transients and noise, use a common-mode choke or a ferrite bead in series with the transmission line, and consider adding a TVS (transient voltage suppressor) diode to protect the DS14C89AN/NOPB from voltage spikes.
• What is the maximum cable length supported by the DS14C89AN/NOPB?
  The maximum cable length supported by the DS14C89AN/NOPB depends on the data rate and the type of cable used. As a general guideline, the maximum cable length is approximately 4000 feet (1219 meters) at a data rate of 115.2 kbps.
