ADM208EARZ-REEL

Overview

The ADM208EARZ-REEL is an RS-232 line transceiver from Analog Devices, operating on a single 5 V supply. It features four drivers and four receivers with full-duplex communication capability. The device supports data rates up to 230 kbps and includes integrated charge pumps requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection and complies with EMC directives. Operating within a temperature range of -40°C to +85°C, it draws 13 mA during normal operation and lacks shutdown functionality.

Feature Summary

• Complies with EU EMC directive for low emissions and high immunity
• Provides robust electrostatic discharge protection on all I/O lines
• Operates from a single 5 V power supply without external transformers
• Includes internal pull-up and pull-down resistors on logic inputs

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging suitable for automated assembly. Confirm the 'E' designation ensures compliance with current environmental standards. Cross-reference the specific package variant RU-24 (TSSOP) against your board layout requirements before finalizing orders.

Selection Notes

Select this component when four independent transmit and receive channels are required. It is suitable for designs needing high ESD tolerance and EMC compliance without complex external circuitry. Avoid if system power management requires a low-power shutdown mode, as this variant does not include that feature.

Part Context

This part belongs to the ADM2xxE family of CMOS RS-232 transceivers. It serves as a plug-in upgrade for older MAX2xx series devices. The ADM208E specifically offers four drivers and four receivers, distinguishing it from the ADM206E which has three receivers.

Replacement Considerations

The ADM208E is backward compatible with earlier ADM2xx products. Direct pin-compatible replacements include other variants within the ADM206E/ADM207E/ADM211E/ADM213E families, provided channel counts and control features align with design needs.
