ADM206EAR

Overview

The ADM206EAR is an RS-232 transceiver from the ADM2xxE family, operating on a single 5 V supply with a guaranteed data rate of 230 kbps. It integrates four drivers and three receivers within a 24-pin SOIC_W package. The device features ±15 kV ESD protection compliant with IEC 1000-4-2 standards and includes shutdown functionality to minimize power consumption. It utilizes internal charge pumps requiring only four external 0.1 μF capacitors for voltage generation.

Feature Summary

• Complies with EU EMC directive 89/336/EEC for low emissions and high immunity
• Provides robust ESD protection up to ±15 kV on all I/O lines
• Includes dedicated shutdown control pins to reduce quiescent current
• Features Schmitt trigger inputs on receivers for noise immunity

Applications

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

Procurement Notes

Verify the specific suffix 'AR' against the official Analog Devices ordering guide to confirm the exact package type and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing systems requiring high-speed RS-232 communication at 230 kbps with strict EMC compliance. It is suitable for applications needing integrated ESD protection without external suppressors. Consider the available packages and pinout compatibility if upgrading from older ADM2xx designs. Verify that the single 5 V supply constraint aligns with the system power architecture.

Part Context

The ADM206EAR belongs to the ADM2xxE series of ruggedized RS-232 line drivers and receivers. This family is designed for harsh electrical environments and offers backward compatibility with earlier ADM2xx products. The 'E' suffix denotes enhanced features such as improved ESD protection and EMC compliance compared to standard variants.

Replacement Considerations

The MAX236EWG+ is listed as a similar replacement option by distributors. Verify pin-to-pin compatibility and functional equivalence, particularly regarding driver/receiver counts and shutdown logic, before substituting.
