Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel specifications. Ensure the component meets the required environmental standards and RoHS compliance status before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high EMI immunity and strict EMC compliance. It is suitable for applications needing multiple receivers and drivers within a compact footprint. Verify that the system architecture can accommodate the necessary external capacitors for the internal charge pump operation.

Part Context

This part belongs to the ADM2xxE family of RS-232 interface devices designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs, offering backward compatibility while providing enhanced ESD protection and lower power consumption features.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a direct plug-in upgrade for MAX2xxE products. Verify pinout compatibility and external capacitor requirements when substituting these components in existing designs.
