ADM207EARUZ-REEL7

Overview

The ADM207EARUZ-REEL7 is an RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply (4.5 V to 5.5 V) and supports data rates up to 230 kbps. The device features five drivers and three receivers, providing full-duplex communication in a 24-lead TSSOP package. It includes internal charge pumps requiring four external 0.1 μF capacitors. The component offers ±15 kV ESD protection on all I/O lines and complies with EMC directives.

Feature Summary

• Complies with EU electromagnetic compatibility directives for low emissions and high immunity
• Provides robust electrostatic discharge protection exceeding ±15 kV on all input/output lines
• Operates reliably in harsh electrical environments without requiring external transient suppressors

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and reel specifications. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical characteristics match the design requirements.

Selection Notes

Select this component when a single 5 V supply operation is required alongside high noise immunity. The ADM207E provides five drivers and three receivers, making it suitable for complex serial interfaces. Its integrated ESD protection eliminates the need for additional suppression components, simplifying the circuit design while maintaining compliance with strict electromagnetic interference standards.

Part Context

This component belongs to the ADM2xxE family of ruggedized RS-232 transceivers designed for harsh electrical environments. It serves as a plug-in upgrade for earlier ADM2xx products, facilitating easy design transitions. The family shares common architectural features, including internal charge pumps and TTL/CMOS compatible logic levels, ensuring backward compatibility with legacy systems.

Replacement Considerations

The ADM206E, ADM208E, ADM211E, and ADM213E are direct replacements within the same family. Verify that the alternative part number matches the required number of drivers and receivers. Confirm that any shutdown or enable control pins present in the substitute do not conflict with the existing board layout if those functions are unused.
