ADM213EARZ

Overview

The ADM213EARZ 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 shutdown and enable control pins; in shutdown mode, the charge pump and transmitters are disabled while two receivers remain active for peripheral monitoring. It complies with the EU EMC directive (89/336/EEC) and offers ±15 kV ESD protection on all I/O lines. The device requires four external 0.1 μF capacitors for its internal charge pump.

Feature Summary

• Complies with the EU directive on electromagnetic compatibility (EMC) including low emissions and high immunity.
• Provides electrostatic discharge protection exceeding ±15 kV on all input and output lines.
• Features a shutdown mode that reduces power consumption to 1 μW while keeping two receivers active.
• Operates from a single 5 V supply using an internal charge pump requiring only four external capacitors.

Applications

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

Procurement Notes

Verify the specific package variant when ordering, as the 'AR' suffix indicates a SOIC_W package. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation. Ensure the design supports the required 5 V supply voltage range and utilizes the correct external capacitor values for the charge pump circuit.

Selection Notes

Select this component for applications requiring high EMI/EMC compliance and robust ESD protection in harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs. Choose this model specifically if the system requires a shutdown state where receiver outputs remain active to monitor peripheral communication events.

Part Context

The ADM213EARZ belongs to the ADM2xxE family of ruggedized RS-232 line drivers and receivers. This family is designed for operation in electrically noisy environments and is backward compatible with earlier ADM2xx products. The device integrates TTL/CMOS inputs and outputs with RS-232 signal levels, utilizing a switched-capacitor technique for voltage conversion.

Replacement Considerations

The datasheet identifies the ADM213EARZ as a plug-in upgrade for MAX2xxE devices. Designers should verify pinout compatibility and electrical characteristics before substituting older generation transceivers with this component.

FAQ

How many receivers remain active during shutdown mode?

During shutdown mode, two receivers (R4 and R5) remain active and enabled, allowing the processor to monitor peripheral devices.

What is the maximum data rate supported by the ADM213EARZ?

The device guarantees a maximum data rate of 230 kbps under worst-case loading conditions.

Does the device require external components for voltage generation?

Yes, the device requires four external 0.1 μF capacitors to support the internal charge pump voltage converter.
