ADM2484EBRWZ

Overview

The ADM2484EBRWZ is an isolated RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single 3 V to 5.5 V supply and supports data rates up to 500 kbps. The device features galvanic isolation with a rated insulation voltage of 2500 Vrms. It includes integrated ESD protection rated at ±15 kV for human-body model and ±15 kV for machine-model standards. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Provides galvanic isolation between the logic interface and the bus line
• Integrates high-voltage ESD protection for robust field operation
• Supports both half-duplex and full-duplex communication modes
• Operates from a single low-voltage power supply

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation
• Multipoint serial communication links

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration and reel specifications. Ensure the procurement channel provides valid traceability for this active component. Cross-reference the ordering part number with the manufacturer's current product selection guide to avoid discrepancies in package type or thermal rating.

Selection Notes

Select this component when designing systems requiring reliable isolation for RS-485 or RS-422 buses. It is suitable for applications needing ±15 kV ESD immunity without external protection components. Consider the 500 kbps data rate limit when evaluating network speed requirements. The single-supply operation simplifies power distribution in embedded environments.

Part Context

This device belongs to the ADM2484E series of isolated transceivers. It shares functional similarities with other members of the family but differs in specific electrical ratings and packaging options. The series is designed to replace traditional optocoupler-based solutions, offering higher reliability and smaller form factors for industrial interface applications.

Replacement Considerations

Consult the Analog Devices product selector guide for direct pin-compatible alternatives within the ADM248x family. Verify that any substitute maintains the required 2500 Vrms isolation rating and ±15 kV ESD protection levels. Ensure the replacement supports the same 3 V to 5.5 V supply voltage range.
