ADM213EARU-REEL7

Overview

The ADM213EARU-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 a guaranteed data rate of 230 kbps. The device 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 and complies with EMC directives. The component utilizes internal charge pumps requiring four external 0.1 μF capacitors and is housed in a TSSOP-28 package.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) with low emissions
• Provides robust ESD protection up to ±15 kV on all I/O lines
• Features shutdown mode reducing power consumption to 1 μW
• Maintains two receiver outputs active during shutdown state

Applications

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

Procurement Notes

Verify the specific ordering suffix RU-REEL7 against the manufacturer's current documentation to confirm the tape-and-reel packaging format and quantity. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the exact part number with official distributor catalogs to confirm availability status and lead times prior to 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 and low power consumption via shutdown modes. Consider the TSSOP package for space-constrained designs. Verify that the 230 kbps data rate meets system requirements and that the specific driver/receiver count aligns with interface needs.

Part Context

This part belongs to the ADM2xxE series of ruggedized RS-232 interfaces designed for harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs, offering backward compatibility. The E-series distinguishes itself through enhanced electromagnetic compatibility and integrated ESD protection, eliminating the need for additional transient suppression components found in earlier generations.

Replacement Considerations

The ADM213EARSZ is a pin-compatible alternative within the same family. Verify that the package type matches the design constraints. Confirm that the functional specifications, particularly the shutdown behavior and data rates, remain consistent with the original design requirements before substitution.
