Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ACPI' against the manufacturer's official datasheet to confirm the industrial temperature grade and isolation voltage ratings. Ensure the ordering quantity matches the standard tube packaging configuration of 14 units per tube. Confirm that the procurement channel provides valid traceability documentation for this specific part number.

Drivers, Receivers, Transceivers Selection Notes

Select this component when isolated RS-485 or RS-422 communication is required in noisy industrial environments. The 2.5 Mbps data rate suits moderate-speed applications. Consider the 28-pin DIP package for prototyping or legacy board designs. Verify that the system design can accommodate the 260 mA operating current and the thermal requirements associated with the specified power dissipation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3480A series, which focuses on providing integrated isolation for serial communication interfaces. Unlike non-isolated variants, this series incorporates internal isolation barriers to protect low-voltage logic from high-voltage transients common in industrial settings. It serves as a critical interface node in distributed control systems where signal integrity and safety are paramount.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific isolation architecture. Check for other MAX3480A variants with different package options or temperature ranges. Cross-reference with other isolated RS-485 transceivers from Analog Devices, ensuring isolation voltage and data rate specifications meet the original design requirements.
