ADM213EARU

Overview

The ADM213EARUZ is a robust RS-232 and V.28 interface device from the ADM2xxE family, operating from a single 5 V power supply. It features four drivers and five receivers with a guaranteed data rate of 230 kbps. The component includes an active-low shutdown control pin (SHDN) and an active-high receiver enable pin (EN). In shutdown mode, the charge pump and transmitters are disabled, while two receivers remain active for peripheral monitoring. It provides ±15 kV ESD protection and complies with EMC directives.

Feature Summary

• Complies with EU EMC directive 89/336/EEC with low emissions
• Provides ±15 kV ESD protection on all I/O lines per IEC 1000-4-2
• Features active-low shutdown and active-high enable control pins
• Maintains two receiver outputs during shutdown for peripheral monitoring

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as RU indicates TSSOP. Confirm RoHS compliance status for the exact part number variant. Check for any recent process change notices or lifecycle status updates directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring high EMI immunity and strict EMC compliance in harsh electrical environments. It serves as a direct plug-in upgrade for MAX2xxE devices. Ensure the design utilizes a single 5 V supply and requires minimal external capacitance for the internal charge pump operation.

Part Context

This device belongs to the ADM2xxE series of ruggedized RS-232 line drivers and receivers. The 'E' designation signifies enhanced electromagnetic compatibility and electrostatic discharge protection compared to standard ADM2xx parts. It is designed for applications where traditional RS-232 transceivers might fail due to environmental noise or static discharge events.

Replacement Considerations

The ADM213EARUZ is documented as a plug-in upgrade for MAX213E devices. Verify pinout compatibility and logic polarity differences between SHDN and EN pins when substituting older generation ADM2xx parts or competing MAX2xxE products.
