ADM213EARS-REEL

Overview

The ADM213EARS-REEL is an RS-232 line transceiver from the ADM2xxE family, designed for single 5 V operation. It integrates four drivers and five receivers with a guaranteed data rate of 230 kbps. The device features ±15 kV ESD protection compliant with IEC 1000-4-2 and low EMI emissions per EN 55022. A shutdown mode reduces power consumption to 1 μW while keeping two receivers active for peripheral monitoring. It utilizes internal charge pumps requiring only four external 0.1 μF capacitors.

Feature Summary

• Complies with EU EMC directive 89/336/EEC for emissions and immunity
• Provides ±15 kV ESD protection on all I/O lines
• Shutdown mode maintains two receiver outputs for peripheral monitoring
• Eliminates need for external TransZorb suppressors

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Ensure the specific revision matches design requirements for EMC performance levels.

Selection Notes

Select this component when high-speed RS-232 communication up to 230 kbps is required alongside strict electromagnetic compatibility standards. The ADM213E variant is specifically chosen over the ADM211E because it retains two receiver channels during shutdown, enabling wake-up functionality from connected peripherals without full system power restoration.

Part Context

This part belongs to the ADM2xxE series, which serves as a robust upgrade to the legacy ADM2xx family. It offers enhanced EMI/EMC performance compared to earlier generations while maintaining backward compatibility in pinout and application circuitry. The E-series designation signifies improved transient protection and lower radiated emissions suitable for modern IT equipment standards.

Replacement Considerations

The ADM213E is a direct plug-in replacement for MAX2xxE devices. Designers upgrading from older ADM2xx parts can utilize existing layouts, though capacitor values should be verified against the new specifications.
