ADM207EAR-REEL

Overview

The ADM207EAR-REEL is an RS-232 transceiver from the ADM2xxE family, manufactured by Analog Devices Inc. It operates on a single 5 V supply and features five drivers and three receivers for full-duplex communication. The device supports data rates up to 230 kbps and includes integrated charge pumps requiring four external 0.1 μF capacitors. It provides ±15 kV ESD protection on all I/O lines and complies with EMC directives. The component is housed in a 24-lead SSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Complies with EU EMC directive 89/336/EEC for low emissions and high immunity
• Provides robust ESD protection up to ±15 kV on all input and output lines
• Operates from a single 5 V power supply using internal charge pumps
• Supports high-speed data transmission rates up to 230 kbps

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 24-lead SSOP configuration. Confirm that the required external capacitors meet voltage and tolerance requirements for the charge pump circuit. Check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring five independent transmitter channels and three receiver channels. It is suitable for applications needing high ESD immunity without external suppressors. Consider the SSOP package constraints for space-limited designs. Verify that the 230 kbps maximum data rate meets the system's baud rate requirements.

Part Context

This part belongs to the ADM2xxE series of ruggedized RS-232 line drivers and receivers. The series offers backward compatibility with earlier ADM2xx products, facilitating upgrades. The ADM207E variant specifically distinguishes itself by providing five drivers and three receivers, unlike the ADM206E which has four drivers and three receivers.
