Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel configuration. Ensure compatibility with existing PCB footprints for the 28-lead SSOP format. Confirm that the component meets RoHS requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and revision level before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-speed RS-232 communication up to 230 kbps with strict EMC compliance needs. The integrated shutdown and enable functions make it suitable for battery-powered portable devices where power management is critical. Verify that the system environment requires ±15 kV ESD protection levels. Ensure the design can accommodate the required four external 0.1 μF capacitors for the charge pump operation.

Part Context

This component belongs to the ADM2xxE family of RS-232 line drivers and receivers manufactured by Analog Devices. The 'E' suffix denotes enhanced features including EMC compliance and superior ESD protection compared to earlier generations. The ADM211E variant specifically provides four drivers and five receivers with full shutdown capability. This family serves as a plug-in upgrade for older MAX2xxE designs, maintaining backward compatibility while offering improved performance in harsh electrical environments.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a plug-in upgrade for MAX2xxE devices. Designers upgrading from older ADM2xx products should verify pinout compatibility. No other specific substitute part numbers are documented in the provided source material.
