ADM206AR-REEL

Overview

The ADM206AR-REEL is a CMOS RS-232 transceiver from Analog Devices, designed for EIA-232-E and V.28 interfaces using a single 5 V supply. It integrates four drivers and three receivers with an active-high shutdown control that reduces power dissipation to less than 5 μW. The device operates at data rates up to 120 kB/s and generates ±10 V internally via charge pumps requiring only four external capacitors. It features Schmitt-trigger inputs with 0.65 V hysteresis and supports industrial temperatures from -40°C to +85°C in a 24-lead SOIC package.

Feature Summary

• Integrates on-board DC-to-DC voltage converters to generate required RS-232 levels from a single 5 V supply
• Features low power shutdown mode reducing consumption to under 5 μW for battery applications
• Includes enable function placing receiver outputs in high impedance state for bus sharing
• Provides latch-up free protection and internal pull-up/pull-down resistors on inputs

Applications

• Battery-powered computers and portable equipment
• Modems and peripheral interface connections
• Printers and industrial instruments
• Microprocessor systems requiring shared data lines

Procurement Notes

Verify the specific ordering suffix matches the required package type and compliance status. The REEL suffix indicates tape and reel packaging suitable for automated assembly. Confirm RoHS compliance requirements against the Z suffix designation if lead-free components are mandated for the target application environment.

Selection Notes

Select this component when four drivers and three receivers are required within a single IC. The ADM206 differs from similar family members by its specific pinout and shutdown logic polarity. Ensure the design accommodates the necessary external capacitors for the charge pump circuit and verify that the 120 kB/s speed meets the system baud rate requirements.

Part Context

This part belongs to the ADM2xx family of line drivers and receivers developed by Analog Devices. It serves as a CMOS enhancement to the earlier AD2xx series, offering improved power efficiency and integrated voltage generation. The ADM206 provides a specific configuration of drivers and receivers distinct from the ADM207 or ADM208 variants within the same product line.

Replacement Considerations

The datasheet notes pin compatibility with MAX206-211/213 devices. Verify electrical specifications and pin assignments before substituting with these equivalents to ensure functional parity in the existing circuit design.
