ADM208EANZ

Overview

The ADM208EANZ is a robust RS-232 line driver and receiver manufactured by Analog Devices. It operates from a single 5 V power supply and integrates an internal charge pump to generate the required ±10 V levels, requiring only four external 0.1 μF capacitors. The device provides four drivers and four receivers with a guaranteed data rate of 230 kbps. It features ±15 kV ESD protection on all I/O lines and complies with EMC directives for low emissions and high immunity. The component is housed in a 24-lead TSSOP package.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) for low emissions and high immunity
• Provides ±15 kV ESD protection on all I/O lines per IEC 1000-4-2 standards
• Operates from a single 5 V supply using an internal charge pump
• Includes Schmitt trigger inputs on receivers for noise immunity

Applications

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

Procurement Notes

Verify the specific ordering suffix EANZ corresponds to the 24-lead TSSOP package variant when sourcing. Confirm that the component meets the required RoHS compliance status for your assembly process. Ensure the supplier provides valid traceability documentation for this Analog Devices part number.

Selection Notes

Select the ADM208EANZ when a 24-pin surface-mount solution is required for RS-232 interfaces. This model offers four drivers and four receivers without shutdown or enable control pins. It is suitable for designs needing high ESD tolerance and EMC compliance within a compact footprint.

Part Context

This component belongs to the ADM2xxE family of RS-232 transceivers designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE devices, maintaining backward compatibility while offering enhanced ESD and EMC performance. The family utilizes CMOS technology to minimize power dissipation.

Replacement Considerations

The ADM208EANZ is functionally compatible with the MAX208E series. Verify pinout alignment and voltage requirements before substitution. Ensure the replacement supports the same 230 kbps data rate and ESD protection levels.
