ADM207EARUZ

Overview

The ADM207EARUZ is a robust RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and features five drivers and three receivers for full-duplex communication. 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, ensuring compliance with EMC directives. The component is housed in a 24-lead TSSOP 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 ±15 kV electrostatic discharge protection on all input and output lines
• Operates from a single 5 V supply using internal charge pump voltage conversion
• Features Schmitt trigger inputs on receivers to ensure error-free reception of noisy signals

Applications

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

Procurement Notes

Verify the specific suffix RUZ confirms the TSSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact pin configuration required for the target PCB layout.

Selection Notes

Select this component when five transmitter channels and three receiver channels are required in a compact surface-mount footprint. It serves as a direct plug-in upgrade for older MAX2xxE designs without requiring schematic changes. Consider the absence of shutdown pins if power management control is not needed for the application.

Part Context

This device belongs to the ADM2xxE family of ruggedized RS-232 transceivers designed for harsh electrical environments. It is backward compatible with earlier ADM2xx products, facilitating easy upgrading of legacy designs. The E-series designation indicates enhanced EMI/EMC performance compared to standard variants.

Replacement Considerations

The ADM207E is functionally equivalent to the MAX207E. Other members of the ADM2xxE family, such as the ADM206E or ADM208E, share similar packaging and interface characteristics but differ in driver and receiver counts.
