ADM207EARU-REEL7

Overview

The ADM207EARU-REEL7 is a robust RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and features five drivers and three receivers. The device supports data rates up to 230 kbps and includes integrated charge pumps requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection on all I/O lines, ensuring compliance with IEC 1000-4-2 standards. The component is housed in a 24-lead TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Complies with the EU directive on electromagnetic compatibility (EMC) for both emissions and immunity.
• Features high-level electrostatic discharge protection exceeding ±15 kV on all input and output lines.
• Includes electrical fast transient burst immunity compliant with IEC 1000-4-4 requirements.
• Eliminates the need for external TransZorb suppressors through internal clamping structures.

Applications

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

Procurement Notes

Verify the specific ordering suffix RU-24 corresponds to the 24-lead TSSOP package configuration required for your design. Confirm that the REEL7 designation matches your automated assembly equipment specifications. Ensure the component meets RoHS directives if applicable to your manufacturing region. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity before procurement.

Selection Notes

Select this component when designing systems requiring five independent transmit channels and three receive channels. It serves as a direct plug-in upgrade for older MAX2xxE series designs without circuit modifications. Choose this device for applications needing high EMI immunity and low power consumption in portable environments. Ensure the system operates within the specified 4.5 V to 5.5 V voltage range for optimal performance.

Part Context

This component belongs to the ADM2xxE family of ruggedized RS-232 interface devices. The family shares common architectural features, including single-supply operation and integrated charge pumps. Variants within the family differ primarily in the number of drivers and receivers, as well as the inclusion of shutdown or enable control pins. The ADM207E specifically lacks these control pins compared to other models in the series.

Replacement Considerations

Public confirmed substitute part numbers include ADM207EARUZ. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part maintains the same ESD protection ratings and EMC compliance levels required by the original design specifications.
