ADM209ARS-REEL

Overview

The ADM209ARS-REEL is a robust RS-232 and V.28 interface transceiver from Analog Devices, operating on a single 5V supply. It features integrated charge pumps to generate required voltage levels without external components. The device provides two drivers and two receivers for full-duplex communication with a data rate of 120 kb/s. It includes ESD protection rated at 15 kV according to IEC 61000-4-2 standards. The part is housed in a 24-lead SSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates need for external capacitors
• High ESD protection rating of 15 kV per IEC 61000-4-2
• Single 5V power supply operation
• Full-duplex RS-232/V.28 interface capability

Applications

• Industrial control systems requiring robust serial communication
• Data acquisition equipment interfaces
• Embedded systems with RS-232 connectivity needs
• Medical instrumentation serial ports

Procurement Notes

Verify the specific suffix 'ARS' indicates the 24-SSOP package variant when sourcing. Confirm RoHS compliance status as indicated by the 'Z' designation in related family parts. Check current availability status as some distributors list this specific reel configuration as obsolete or limited supply. Ensure compatibility with existing PCB footprint for 24-lead SSOP mounting.

Selection Notes

Select this component for applications requiring high ESD immunity in single-supply environments. The integrated charge pump simplifies design compared to older transceivers needing multiple voltage rails. Consider the 120 kb/s speed limit for slower serial links. The wide industrial temperature range suits harsh environments. Verify that the 24-pin SSOP package fits the target board layout constraints.

Part Context

This part belongs to the ADM2xxE family of robust RS-232 transceivers from Analog Devices. The family shares common features like integrated charge pumps and high ESD protection. Variants differ primarily by package type (SOIC, SSOP) and pin count. The ADM209 specifically offers two drivers and receivers in a compact 24-lead form factor suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include other ADM2xxE family members with similar pinouts and functionality. Cross-reference package dimensions for 24-SSOP equivalents. Verify electrical parameters match the 120 kb/s speed and 5V supply requirements. Check if alternative manufacturers offer pin-compatible RS-232 transceivers with comparable ESD ratings.
