ADM208EARSZ

Overview

The ADM208EARSZ is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply with a range of 4.5 V to 5.5 V and draws 13 mA during normal operation. The device features four drivers and four receivers, supporting data rates up to 230 kbps. 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 and functions within an operating 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 input/output lines
• Operates from a single 5 V supply using only four external capacitors
• Supports high-speed data transmission up to 230 kbps

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 that the component meets RoHS compliance requirements for your region. Ensure the supplier provides valid traceability documentation for this Analog Devices part number to guarantee authenticity and quality standards.

Selection Notes

Select the ADM208EARSZ when four independent transmit and receive channels are required without shutdown control. This model lacks the enable and shutdown pins found in the ADM211E or ADM213E variants. It is suitable for designs where continuous operation is preferred over power-saving modes. Verify that the SSOP-24 footprint matches the PCB layout constraints.

Part Context

The ADM208EARSZ belongs to the ADM2xxE family of ruggedized RS-232 interface devices. This series is designed for harsh electrical environments and offers backward compatibility with earlier ADM2xx products. The E-series designation indicates enhanced EMC compliance and improved ESD protection compared to standard versions. It serves as a direct upgrade path for legacy designs requiring robust serial communication interfaces.

Replacement Considerations

The MAX208EEWG+ is a publicly confirmed substitute part number offering similar functionality. Both devices provide four drivers and receivers with comparable voltage and speed specifications. Verify pin-to-pin compatibility and ensure the replacement package type matches the existing board design before implementation.
