MAX487ECSA+T Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the MAX487ECSA+T?
  The recommended operating voltage range for the MAX487ECSA+T is 4.5V to 5.5V.
• How do I ensure reliable communication with the MAX487ECSA+T in noisy environments?
  To ensure reliable communication in noisy environments, use a common-mode choke or a ferrite bead in series with the RS-485 bus, and consider using a shielded cable to reduce electromagnetic interference (EMI).
• What is the maximum cable length supported by the MAX487ECSA+T?
  The maximum cable length supported by the MAX487ECSA+T depends on the data rate and cable characteristics, but a general guideline is to limit the cable length to 4000 feet (1219 meters) at 10 Mbps.
• How do I configure the MAX487ECSA+T for half-duplex or full-duplex operation?
  The MAX487ECSA+T can be configured for half-duplex or full-duplex operation by connecting the DE (driver enable) pin to the RE (receiver enable) pin for half-duplex, or by connecting the DE pin to VCC and the RE pin to GND for full-duplex.
• What is the thermal shutdown temperature of the MAX487ECSA+T?
  The thermal shutdown temperature of the MAX487ECSA+T is typically 150°C, at which point the device will shut down to prevent damage from overheating.
