ADM213EARSZ

Overview

The ADM213EARSZ is a robust RS-232 and V.28 interface device from the ADM2xxE family, manufactured by Analog Devices Inc. It operates from a single 5 V power supply (4.5 V to 5.5 V) and features four drivers and five receivers with full-duplex communication capability. The component 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 device incorporates shutdown and enable control pins, drawing 13 mA during operation and reducing current to 1 μW in shutdown mode. It is housed in a 28-lead SSOP 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
• Eliminates the need for external TransZorb suppressors through integrated transient protection

Applications

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

Procurement Notes

Verify the specific ordering suffix 'ARSZ' corresponds to the SSOP-28 package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the procurement channel sources directly from Analog Devices or authorized distributors to guarantee authenticity. Check for any recent product change notices regarding packaging or pinout modifications before finalizing orders.

Selection Notes

Select this component when designing systems requiring high EMI/EMC immunity and ±15 kV ESD protection without external suppressors. It is suitable for applications needing a shutdown mode that retains receiver functionality for peripheral monitoring. Choose this part over standard RS-232 transceivers if operating in harsh electrical environments or where battery life is critical due to its low shutdown power consumption.

Part Context

The ADM213EARSZ belongs to the ADM2xxE family of ruggedized RS-232 line drivers and receivers. This family is designed as a plug-in upgrade for older MAX2xxE devices, offering backward compatibility. The ADM213E specifically distinguishes itself by maintaining two active receivers during shutdown, unlike the ADM211E which disables all receivers. It shares core features like the single 5 V supply operation and internal charge pump with other members of the series.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a plug-in upgrade for MAX2xxE devices. Verify pinout compatibility and logic level thresholds when substituting with other RS-232 transceivers. Ensure the replacement part supports the required 230 kbps data rate and ±15 kV ESD protection levels.
