ADM206EAR-REEL

Overview

The ADM206EAR-REEL is an RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and features four drivers and three receivers. The device supports data rates up to 230 kbps and includes shutdown functionality with 1 μW power consumption. It provides ±15 kV ESD protection on all I/O lines and complies with EMC directives. The component is housed in a TSSOP package and requires four external 0.1 μF capacitors for operation.

Feature Summary

• Complies with EU electromagnetic compatibility (EMC) directives, including low emissions and high immunity to radiated interference.
• Provides robust electrostatic discharge (ESD) protection of ±15 kV on all input and output lines.
• Features a shutdown mode that disables the charge pump and transmitters to minimize quiescent current.
• Includes internal pull-up resistors on TTL/CMOS inputs and pull-down resistors on RS-232 inputs.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure the component meets required environmental standards such as RoHS compliance before integration into final designs.

Selection Notes

Select this component for applications requiring high-speed RS-232 communication up to 230 kbps with integrated ESD protection. Consider the shutdown feature for battery-powered systems to extend operational life. Verify pin compatibility when upgrading from older ADM2xx series devices.

Part Context

The ADM206E belongs to the ADM2xxE family of ruggedized RS-232 interface devices. This family is designed for harsh electrical environments and offers backward compatibility with earlier ADM2xx products. The ADM206E specifically provides four drivers and three receivers within a compact package.

Replacement Considerations

The ADM206E serves as a plug-in upgrade for MAX2xxE devices. It is backward compatible with earlier ADM2xx products, facilitating easy design upgrades without significant circuit modifications.

FAQ

What is the maximum data rate supported by the ADM206E?

The ADM206E supports data rates up to 230 kbps under worst-case loading conditions.

How does the shutdown function affect the ADM206E?

In shutdown mode, the charge pump is disabled, all transmitters are turned off, and all receiver outputs are placed in a high impedance state, reducing power consumption to 1 μW.

What level of ESD protection does the ADM206E provide?

The device provides ±15 kV ESD protection on all I/O lines according to the Human Body Model and IEC 1000-4-2 air-gap discharge standards.
