ADM207EARS-REEL

Overview

The ADM207EARS-REEL is an RS-232 transceiver from the ADM2xxE family, manufactured by Analog Devices Inc. It operates on a single 5 V 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 and complies with EMC directives. The component is housed in a 24-lead SSOP package (suffix RS) and is supplied in reel packaging.

Feature Summary

• Complies with EU EMC directive 89/336/EEC for low emissions and high immunity
• Provides robust ESD protection up to ±15 kV on all input and output lines
• Operates from a single 5 V power supply without requiring negative voltage rails
• Includes internal pull-up and pull-down resistors on logic inputs

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. The 'RS' suffix indicates a 24-lead SSOP package, while 'REEL' denotes bulk reel packaging. Confirm RoHS compliance status as specifications may vary by manufacturing revision. Ensure the source document matches the exact part number to avoid confusion with similar ADM2xxE variants that may have different driver/receiver counts or control pins.

Selection Notes

Select this component when designing systems requiring five transmit channels and three receive channels for RS-232 communication. It is suitable for applications needing high ESD tolerance and EMC compliance without external suppressors. Verify that the system operates within the 4.5 V to 5.5 V supply range and requires no shutdown or enable control signals, as this variant lacks those pins. Ensure the PCB layout accommodates the 24-lead SSOP footprint and the required four external capacitors for the charge pump.

Part Context

The ADM207E is part of the ADM2xxE family of ruggedized RS-232 interface devices. This family shares common architecture, including the single-supply charge pump and ESD protection scheme. Unlike the ADM211E or ADM213E, the ADM207E does not feature shutdown or enable control pins, making it a simpler solution for always-on serial interfaces. It serves as a plug-in upgrade for older MAX2xxE designs.

Replacement Considerations

Public confirmed substitute part numbers include ADM207EARUZ.
