ST485ERBN Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the ST485ERBN is approximately 1200 meters, assuming a cable with a characteristic impedance of 100 ohms and a propagation delay of 5 ns/m.
  • To ensure reliable communication over long distances, it is recommended to use a twisted pair cable, maintain a consistent impedance throughout the transmission line, and implement proper termination and biasing at the receiver end.
  • Yes, the ST485ERBN can be used in a multi-point or multi-drop configuration, but it is essential to ensure that the total bus capacitance does not exceed 250 pF to maintain signal integrity.
  • The recommended operating temperature range for the ST485ERBN is -40°C to 125°C, but it can operate up to 150°C for short periods of time.
  • To protect the ST485ERBN from ESD and surge events, it is recommended to use external protection devices such as TVS diodes or surge protectors, and follow proper PCB layout and design guidelines.
