ADM207EARU

Overview

The ADM207EARU is a fully compliant RS-232 line transceiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and integrates five drivers and three receivers within a 24-lead TSSOP package. The device supports data rates up to 230 kbps and includes an internal charge pump 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. Operating temperatures range from -40°C to +85°C, with a typical quiescent current of 13 mA.

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
• Integrates a charge pump voltage converter eliminating the need for dual supplies
• Features Schmitt trigger inputs on receivers to ensure error-free reception in noisy environments

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific RU suffix indicates the TSSOP package variant. Check for RoHS compliance status as manufacturing processes may evolve. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component when designing systems requiring five independent transmit channels and three receive channels. It is suitable for applications needing high-speed data transmission up to 230 kbps. Consider its space-saving TSSOP package for dense PCB layouts. Verify that the single 5 V supply constraint aligns with the system power architecture.

Part Context

This part belongs to the ADM2xxE family of ruggedized RS-232 interface devices. It serves as a plug-in upgrade for older MAX2xxE series products, facilitating design modernization. The device maintains backward compatibility while offering enhanced EMC performance and lower power consumption compared to previous generations.

Replacement Considerations

The ADM207EARUZ is listed as a parameter-equivalent replacement. Other similar options include the MAX207CDB and MAX207IDBR from Texas Instruments. Verify pinout compatibility and electrical specifications before substituting.
