ADM213EARUZ

Overview

The ADM213EARUZ 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 four drivers and five receivers with full-duplex communication capability. 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 and complies with EMC directives. The component is housed in a 28-lead TSSOP package and functions within a 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 ESD protection on all I/O lines per IEC 1000-4-2 standards
• Features shutdown mode that disables the charge pump and transmitters while keeping two receivers active
• 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 the package type, as variations exist within the family. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing systems requiring high ESD immunity and EMC compliance for portable applications. The unique shutdown feature allows monitoring of peripheral devices even when the main system is powered down. Verify that the required data rate does not exceed 230 kbps and that the application environment falls within the specified operating temperature range.

Part Context

The ADM213E belongs to the ADM2xxE family of RS-232 interface devices designed for harsh electrical environments. This family offers backward compatibility with earlier ADM2xx products, facilitating easy upgrades. The ADM213E specifically distinguishes itself by maintaining two receiver outputs during shutdown, unlike other family members that disable all receivers.

Replacement Considerations

The MAX2xxE series serves as a plug-in upgrade alternative. Verify pinout compatibility and logic level thresholds before substitution. Ensure the replacement part meets the same ESD and EMC requirements if used in regulated environments.
