MAX485ECSA-T Frequently Asked Questions (FAQs)

• What is the maximum data rate that the MAX485ECSA-T can support?
  The MAX485ECSA-T can support data rates up to 10 Mbps, making it suitable for high-speed serial communication applications.
• How does the MAX485ECSA-T handle common-mode noise and electromagnetic interference (EMI)?
  The MAX485ECSA-T has a high common-mode rejection ratio (CMRR) of 80 dB, which helps to reject common-mode noise and EMI. Additionally, it has a high electrostatic discharge (ESD) protection of ±15 kV, making it suitable for use in noisy environments.
• What is the maximum cable length that can be used with the MAX485ECSA-T?
  The maximum cable length that can be used with the MAX485ECSA-T depends on the data rate and the type of cable used. As a general rule, the maximum cable length is inversely proportional to the data rate. For example, at a data rate of 10 Mbps, the maximum cable length is approximately 100 meters. However, this can be extended to several kilometers at lower data rates.
• Can the MAX485ECSA-T be used in half-duplex mode?
  Yes, the MAX485ECSA-T can be used in half-duplex mode by connecting the DE (driver enable) and RE (receiver enable) pins together. This allows the transmitter and receiver to share the same bus, enabling half-duplex communication.
• What is the power consumption of the MAX485ECSA-T?
  The power consumption of the MAX485ECSA-T depends on the operating mode and the supply voltage. In normal operation, the power consumption is typically around 30 mW. However, in shutdown mode, the power consumption can be as low as 1 μW, making it suitable for battery-powered applications.
