ADM208EARUZ-REEL

Overview

The ADM208EARUZ-REEL is a single-supply RS-232 transceiver from Analog Devices, operating on a 5 V power rail. It integrates four drivers and four receivers within a 24-lead TSSOP package. The device supports data rates up to 230 kbps and includes an internal charge pump requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection compliant with IEC 1000-4-2 standards and meets EMC directives for low emissions.

Feature Summary

• Complies with EU electromagnetic compatibility (EMC) directives including EN 55022
• Provides robust electrostatic discharge protection exceeding ±15 kV on all I/O lines
• Features high slew rate control to minimize electromagnetic interference emissions
• Eliminates the need for external TransZorb suppressors through integrated protection

Applications

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

Procurement Notes

Verify that the ordering suffix RUZ corresponds specifically to the TSSOP-24 package variant. Confirm the REEL designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure component authenticity and revision level accuracy.

Selection Notes

Select this component when designing systems requiring four independent RS-232 channels in a compact surface-mount footprint. It serves as a direct plug-in upgrade for legacy MAX2xxE designs. Ensure the application environment requires compliance with strict EMC emission limits and high ESD immunity without additional external suppression components.

Part Context

This component belongs to the ADM2xxE family of ruggedized RS-232 interface devices manufactured by Analog Devices. The family shares common architectural features such as single-supply operation and integrated charge pumps. The ADM208E variant specifically distinguishes itself by providing four drivers and four receivers, unlike other family members with different channel counts or shutdown capabilities.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a plug-in upgrade for MAX2xxE devices. Designers migrating from older generations should verify pinout compatibility and capacitor requirements before substitution.
