ADM207EARSZ

Overview

The ADM207EARSZ 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 ±15 kV ESD protection compliant with IEC 1000-4-2 standards. It utilizes four external 0.1 μF capacitors for charge pump operation. The component is housed in a 24-lead SSOP package and functions within a temperature range of -40°C to +85°C.

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 I/O 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 ARSZ corresponds to the SSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the procurement channel provides valid traceability for industrial-grade components.

Selection Notes

Select this model for designs requiring five transmitter channels and three receiver channels. It serves as a plug-in upgrade for older MAX2xxE designs. Verify that the application does not require shutdown control pins, as this specific variant lacks enable and shutdown functionality.

Part Context

This component belongs to the ADM2xxE series of EMI/EMC-compliant RS-232 line drivers and receivers. The 'E' designation indicates enhanced electromagnetic compatibility features compared to standard ADM2xx parts. It is part of a broader family including ADM206E, ADM208E, ADM211E, and ADM213E.

Replacement Considerations

The ADM207EARSZ is backward compatible with earlier ADM2xx products. Direct pin-compatible upgrades may include other variants within the ADM2xxE family, provided driver/receiver counts match. Verify package dimensions for SSOP-24 compatibility.
