ADM207EARZ-REEL

Overview

The ADM207EARZ-REEL is an RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and provides five drivers and three receivers. The device supports data rates up to 230 kbps and includes internal charge pumps requiring four external 0.1 μF capacitors. It features ±15 kV ESD protection on all I/O lines, complies with the EU EMC directive, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Complies with the EU directive on electromagnetic compatibility (EMC) for both emissions and immunity.
• Provides robust electrostatic discharge (ESD) protection exceeding ±15 kV on all input/output lines.
• Operates from a single 5 V power supply using internal voltage converters.
• 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 that the ordering suffix 'RZ' corresponds to the specific lead-free RoHS-compliant tape and reel packaging configuration intended for automated surface-mount assembly. Confirm the component revision matches the required design specifications before finalizing procurement orders.

Selection Notes

Select this model when a single 5 V supply interface is required without shutdown or enable control pins. It serves as a direct replacement for older ADM2xx series devices. Ensure the application requires five transmitter channels and three receiver channels to match the pinout configuration.

Part Context

This component belongs to the ADM2xxE family of ruggedized RS-232 transceivers designed for harsh electrical environments. The family shares common architecture but varies in channel count and control features. This specific part lacks the shutdown functionality found in other variants like the ADM211E.

Replacement Considerations

The datasheet indicates backward compatibility with earlier ADM2xx products, facilitating easy upgrading of older designs. Verify pin-to-pin compatibility with legacy MAX2xxE devices if migrating from competitor platforms.

FAQ

Does the ADM207E include shutdown or enable control pins?

No, the ADM207E does not feature shutdown or enable control pins; these functions are available on other family members such as the ADM211E and ADM213E.

What is the maximum guaranteed data rate for this device?

The device guarantees a maximum data rate of 230 kbps under worst-case loading conditions.

How many external capacitors are required for operation?

Four external 0.1 μF capacitors are required to support the internal charge pump voltage converters.
