• Complies with EU EMC directive for low emissions and high immunity
• Provides robust ESD protection against contact and air-gap discharges
• Operates from a single 5 V power supply without external transformers
• Supports high-speed data transmission up to 230 kbps

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the reel packaging format. Confirm that the component matches the exact Analog Devices part number. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for the batch received.

Selection Notes

Select this component when designing systems requiring four-channel RS-232 communication. It is suitable for applications needing high ESD tolerance and EMC compliance. Consider the 24-lead SOIC package dimensions for PCB layout constraints. Verify that the 5 V supply voltage aligns with the system's power architecture.

Part Context

This component belongs to the ADM2xxE family of RS-232 transceivers. It is designed as a plug-in upgrade for older MAX2xxE devices. The family shares common features like single-supply operation and integrated charge pumps. Other members include the ADM206E, ADM207E, ADM211E, and ADM213E.

Replacement Considerations

The ADM208EARSZ is a pin-compatible alternative available in SSOP-24 packaging. Both parts share identical electrical specifications and functionality. Verify the package type requirement before substituting.
