ADM213EAR

Overview

The ADM213EAR is a robust RS-232 and V.28 interface device operating from a single 5 V power supply, compliant with the EU EMC directive. It features four drivers and five receivers with a guaranteed data rate of 230 kbps. The component includes shutdown and enable control pins; in shutdown mode, the charge pump and three receivers are disabled while two receivers remain active for peripheral monitoring. It provides ±15 kV ESD protection on all I/O lines and utilizes internal pull-up and pull-down resistors.

Feature Summary

• Complies with the EU directive on electromagnetic compatibility (EMC) including low EMI emissions
• Provides high-level electrostatic discharge protection up to ±15 kV on all input and output lines
• Features a shutdown mode that reduces power consumption to 1 μW while keeping two receivers active
• Includes an internal charge pump requiring only four external capacitors for operation

Applications

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

Procurement Notes

Verify the specific package suffix against the manufacturer's ordering guide to ensure correct physical dimensions and pinout compatibility. Confirm RoHS compliance status and lead-free specifications as required by your assembly processes. Cross-reference the exact part number with official distributor catalogs to validate current availability and revision levels before finalizing procurement.

Selection Notes

Select this component when designing systems requiring high EMI immunity and strict EMC compliance without external suppressors. It is suitable for applications needing a single 5 V supply with integrated voltage conversion. Consider the unique shutdown behavior where two receivers remain active if peripheral monitoring during low-power states is required.

Part Context

The ADM213EAR belongs to the ADM2xxE family of ruggedized RS-232 line drivers and receivers. This series is designed for harsh electrical environments and serves as a plug-in upgrade for older MAX2xxE designs. The 'E' designation indicates enhanced EMC and ESD protection capabilities compared to standard industrial grade counterparts.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a plug-in upgrade for MAX2xxE devices. Verify pin-to-pin compatibility and logic level thresholds when substituting other RS-232 transceivers. Ensure any replacement supports the required 230 kbps data rate and single 5 V supply operation.
