ADM211EARZ-REEL

Overview

The ADM211EARZ-REEL is an RS-232 line transceiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and supports data rates up to 230 kbps. The device integrates four drivers and five receivers, providing full-duplex communication capabilities. It features ±15 kV ESD protection on all I/O lines and complies with the EU EMC directive (89/336/EEC). The component utilizes internal charge pumps requiring only four external 0.1 μF capacitors. Key control functions include shutdown and enable pins, allowing for low-power operation with a shutdown current of 1 μW. It is housed in a 28-lead SOIC_W package.

Feature Summary

• Complies with EU EMC directive and provides high immunity against radiated and conducted interference.
• Features robust electrostatic discharge protection exceeding ±15 kV on all input and output lines.
• Integrates internal DC-to-DC converters eliminating the need for external voltage inverters or additional power supplies.
• Includes dedicated shutdown and enable control pins to minimize quiescent power consumption during idle states.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. Confirm RoHS compliance status and lead-free soldering requirements against the latest manufacturer documentation. Ensure the procurement channel provides valid traceability for Analog Devices components. Check for any regional distribution restrictions or export controls applicable to this part number before finalizing orders.

Selection Notes

Select the ADM211EARZ-REEL when designing systems requiring four drivers and five receivers within a single interface IC. This model is appropriate for applications needing active shutdown functionality to reduce power consumption. Consider the 28-lead SOIC_W package dimensions for PCB layout constraints. Verify that the system environment requires the specified ±15 kV ESD protection levels and EMC compliance standards.

Part Context

This component belongs to the ADM2xxE family of RS-232 transceivers designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs while maintaining backward compatibility with earlier ADM2xx products. The device represents an enhancement over standard RS-232 interfaces by integrating advanced EMI suppression and transient protection directly into the CMOS architecture.

Replacement Considerations

The datasheet identifies the ADM211E as the base model for this component. Other members of the ADM2xxE family may offer similar functionalities but differ in driver/receiver counts or pin configurations. Verify pinout compatibility and logic thresholds when substituting with other devices in the series.
