ADM213EARUZ-REEL7

Overview

The ADM213EARUZ-REEL7 is an RS-232 line transceiver from the ADM2xxE family, manufactured by Analog Devices. It operates on a single 5 V power supply and features four drivers and five receivers with full-duplex communication capability. The device supports data rates up to 230 kbps and includes shutdown and enable control pins. It utilizes internal charge pumps requiring only four external 0.1 μF capacitors. The component provides ±15 kV ESD protection and complies with EMC directives.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) for low emissions and high immunity
• Provides robust ESD protection exceeding ±15 kV on all I/O lines
• Features shutdown mode that disables the charge pump and most receivers while keeping two receivers active
• Operates from a single 5 V supply using an internal voltage doubler and inverter

Applications

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

Procurement Notes

Verify the specific ordering suffix RUZ corresponds to the TSSOP-28 package and REEL7 indicates tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor specifications before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high EMI/EMC immunity and robust ESD protection for RS-232 interfaces. It is suitable for applications needing a shutdown feature that maintains receiver activity for peripheral monitoring while minimizing power consumption. Ensure the design accommodates the TSSOP-28 package dimensions and thermal requirements.

Part Context

This part belongs to the ADM2xxE series of ruggedized RS-232 transceivers designed for harsh electrical environments. The 'E' designation signifies enhanced EMI/EMC compliance and superior ESD protection compared to standard ADM2xx devices. It serves as a plug-in upgrade for older MAX2xxE designs, maintaining backward compatibility while offering improved performance characteristics.

Replacement Considerations

The ADM213EARSZ is a pin-compatible alternative available in an SSOP-28 package. Designers should verify package footprint differences between TSSOP and SSOP variants during replacement planning.
