ADM213EARSZ-REEL

Overview

The ADM213EARSZ-REEL is a robust RS-232 and V.28 interface device manufactured by Analog Devices Inc., 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, allowing two receivers to remain active during shutdown for peripheral monitoring. It provides ±15 kV ESD protection on all I/O lines and complies with the EU EMC directive (89/336/EEC). The device utilizes an internal charge pump requiring only four external 0.1 μF capacitors. It operates within a temperature range of -40°C to +85°C and is housed in a 28-lead SSOP package.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) with low EMI emissions and high immunity to fast transient bursts.
• Provides robust electrostatic discharge protection up to ±15 kV on all input and output lines.
• Features a dedicated shutdown mode that reduces power consumption to 1 μW while keeping two receivers active.
• Includes internal charge pumps to generate required voltage levels from a single 5 V supply.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints for the 28-lead SSOP configuration. Confirm environmental compliance requirements such as RoHS status prior to finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high ESD tolerance and EMC compliance without external suppressors. It is suitable for battery-operated applications due to its ultra-low shutdown current. Consider the unique shutdown behavior where two receivers remain active if peripheral monitoring is required during low-power states.

Part Context

This part belongs to the ADM2xxE family of RS-232 transceivers designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs, maintaining backward compatibility while offering enhanced EMC performance and lower power consumption through advanced CMOS technology.

Replacement Considerations

The ADM213EARSZ-REEL is functionally compatible with the MAX213E series. Verify pinout alignment and logic level thresholds when substituting to ensure seamless integration into existing circuit designs without hardware modifications.

FAQ

How many receivers remain active when the ADM213E is in shutdown mode?

Two receivers (R4 and R5) remain active during shutdown, allowing the device to monitor peripheral devices while other components are powered down.

What is the maximum data rate supported by the ADM213E?

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

Does the ADM213E require external components for voltage generation?

Yes, it requires four external capacitors (typically 0.1 μF) connected to the charge pump pins to generate the necessary positive and negative voltages from a single 5 V supply.
