ADM1486ARZ

Overview

The ADM1486ARZ is a half-duplex differential line transceiver designed for high-speed bidirectional data communication on multipoint bus transmission lines. Operating from a single 5 V power supply, it complies with EIA RS-485 and RS-422 standards and is recommended for PROFIBUS applications. The device features a 30 Mbps data rate, low power consumption of 0.8 mA, and integrated thermal shutdown and short-circuit protection. It is housed in an 8-lead SOIC package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Complies with EIA RS-485 and RS-422 standards
• Integrated thermal shutdown and short-circuit protection
• Fail-safe receiver feature for open-circuit inputs

Applications

• Industrial field equipment
• PROFIBUS applications
• Multipoint bus transmission lines

Procurement Notes

Verify the component against official Analog Devices documentation to confirm specifications and authenticity. Ensure the ordering suffix matches the required packaging format, such as tube or reel variants. Cross-reference the manufacturer part number with authorized distributors to validate availability and compliance with current RoHS directives before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high-speed differential communication up to 30 Mbps. It is suitable for environments needing robust protection against bus contention and excessive power dissipation. Consider the 8-lead SOIC package constraints and verify that the system design accommodates the specified common-mode voltage range and power supply requirements.

Part Context

The ADM1486ARZ belongs to the ADM1486 series of RS-485/RS-422 transceivers manufactured by Analog Devices Inc. This series is engineered for balanced data transmission on multipoint buses. The ARZ designation indicates a lead-free version packaged in a standard 8-lead narrow body SOIC format, suitable for surface mount assembly in industrial and commercial electronic systems.

Replacement Considerations

The datasheet identifies the SN65ALS1176 as a comparable device, noting the ADM1486 as a superior upgrade. Verify pin compatibility and electrical characteristics when substituting other RS-485 transceivers in existing designs.
