ADM211EARUZ

Overview

The ADM211EARUZ is a robust RS-232 line transceiver from the ADM2xxE family, manufactured by Analog Devices Inc. It operates on a single 5 V power supply and supports data rates up to 230 kbps. The device integrates four drivers and five receivers within a 28-lead TSSOP package. It features ±15 kV ESD protection compliant with IEC 1000-4-2 standards and includes shutdown and enable control pins for power management. The internal charge pump requires only four external 0.1 μF capacitors.

Feature Summary

• Complies with EU EMC directive 89/336/EEC for low emissions and high immunity
• Provides ±15 kV ESD protection on all I/O lines per IEC 1000-4-2 standard
• Integrates shutdown mode reducing power consumption to 1 μW
• Includes enable pin functionality for receiver output tristating

Applications

• Laptop computers
• Notebook computers
• Printers
• Peripherals
• Modems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the component matches the required lead-free specifications if applicable to your assembly process.

Selection Notes

Select this component when designing systems requiring high ESD immunity and strict EMC compliance in portable devices. The integrated shutdown feature makes it suitable for battery-operated applications where minimizing quiescent current is critical. Verify that the 230 kbps data rate meets the requirements of the target serial communication interface.

Part Context

This part belongs to the ADM2xxE series of ruggedized RS-232 transceivers designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs while offering enhanced EMI/EMC performance. The device maintains backward compatibility with earlier ADM2xx products, facilitating easy design upgrades.

Replacement Considerations

The ADM211EARSZ (SSOP-28) and ADM211EARZ (SOIC-28) are direct functional equivalents within the same family. These alternatives offer identical electrical characteristics but utilize different physical packages. Verify pinout compatibility and thermal requirements before substituting.
