MAX487ECPA datasheet by Maxim Integrated Products

MAX487ECPA Frequently Asked Questions (FAQs)

• What is the maximum data rate that the MAX487ECPA can support?
  The MAX487ECPA can support data rates up to 1 Mbps, making it suitable for most industrial and commercial applications.
• How does the MAX487ECPA handle common-mode voltage?
  The MAX487ECPA has a common-mode voltage range of ±15V, which allows it to operate in noisy environments and provides high immunity to electromagnetic interference (EMI).
• What is the purpose of the enable pin (EN) on the MAX487ECPA?
  The enable pin (EN) is used to put the device in a low-power shutdown mode when driven low, which reduces the supply current to less than 1µA. This feature is useful for power-sensitive applications.
• Can the MAX487ECPA be used in a multi-point application?
  Yes, the MAX487ECPA can be used in a multi-point application, but it requires an external diode array to prevent backfeed of the transmitter output into the receiver input.
• How does the MAX487ECPA protect against ESD and EFT?
  The MAX487ECPA has built-in electrostatic discharge (ESD) protection up to ±15kV and electrical fast transient (EFT) protection up to ±2kV, which helps to ensure reliable operation in harsh environments.
