ADM206EARZ

Overview

The ADM206EARZ is an RS-232 transceiver from Analog Devices operating on a single 5 V supply. It features four drivers and three receivers with full-duplex communication capability at data rates up to 230 kbps. The device includes shutdown functionality consuming 1 μW and supports ±15 kV ESD protection. It operates within a voltage range of 4.5 V to 5.5 V, drawing 7 mA during active operation. The component is housed in a 24-pin SSOP package and functions reliably between -40°C and +85°C.

Feature Summary

• Complies with EMC directives including low EMI emissions and high immunity to fast transient bursts.
• Provides robust electrostatic discharge protection on all I/O lines without external suppressors.
• Integrates internal charge pumps requiring only small external capacitors for voltage generation.
• Includes dedicated control pins for enabling receivers and shutting down the device to minimize power consumption.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the selected package variant. Confirm that the required external capacitor values align with the official design guidelines for optimal performance.

Selection Notes

Select this component when designing systems requiring high ESD tolerance and EMC compliance in space-constrained environments. Consider the integrated shutdown feature for battery-powered applications where minimizing quiescent current is critical. Verify that the 230 kbps data rate meets the requirements of the target serial communication interface.

Part Context

This part belongs to the ADM2xxE family of RS-232 line drivers and receivers designed for harsh electrical environments. The series offers backward compatibility with earlier ADM2xx products, facilitating upgrades. The E designation indicates enhanced ESD protection and EMC compliance compared to standard variants.

Replacement Considerations

The ADM206EARZ serves as a plug-in upgrade for MAX2xxE devices. Designers migrating from older generations should verify pinout compatibility and ensure that external component values meet the new specifications for reliable operation.
