Instructions for Using the MAX488CSA

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V.
    • Connect VCC to the power supply and GND to ground.
  2. Data Lines:

    • Connect the differential data lines (A and B) to the corresponding pins on the MAX488CSA.
    • For RS-485 communication, connect the A and B lines to the appropriate transceiver or bus.
    • For RS-422 communication, use separate A/B pairs for each direction.
  3. Receiver Inputs:

    • Connect the receiver inputs (Y and Z) to the microcontroller or other logic circuitry.
    • The receiver input impedance is between 12kΩ and 16kΩ, which helps in matching the characteristic impedance of the transmission line.
  4. Driver Outputs:

    • Connect the driver outputs (RO) to the microcontroller or other logic circuitry.
    • Ensure the output current does not exceed 10mA to avoid damage.
  5. Data Rate:

    • The MAX488CSA supports data rates up to 2.5Mbps. Ensure the data rate is within this limit to maintain reliable communication.
  6. Temperature Considerations:

    • Operate the device within the commercial temperature range of 0°C to 70°C.
    • Store the device within the storage temperature range of -40°C to 125°C.
  7. Propagation Delay and Skew:

    • The propagation delay from the transmitter to the receiver is typically 350ns.
    • The skew between the differential signals is typically 50ns. Ensure these parameters are accounted for in your system design.
  8. Input Voltage Range:

    • The input voltage range for differential signals is -7V to 12V. Ensure the input signals do not exceed these limits to prevent damage.
  9. Common-Mode Input Voltage:

    • The common-mode input voltage range is also -7V to 12V. This ensures compatibility with a wide range of signal levels.

By following these instructions, you can ensure reliable operation of the MAX488CSA in your RS-485/RS-422 communication systems.
