ADM206ARZ-REEL

Overview

The ADM206ARZ-REEL is a CMOS RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single +5 V supply, utilizing internal charge pumps to generate the ±10 V required for EIA-232-E compliance. The device integrates four drivers and three receivers with a data rate capability of 120 kB/s. Key electrical parameters include a power supply voltage range of 4.5 V to 5.5 V, a typical operating current of 7 mA, and a low-power shutdown mode consuming less than 5 μW. It features Schmitt-trigger inputs with hysteresis and supports TTL/CMOS logic levels.

Feature Summary

• Integrates on-board DC-to-DC converters to generate required RS-232 voltages from a single 5 V supply
• Features low power shutdown mode reducing dissipation 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 ±30 V receiver input level tolerance

Applications

• Battery-powered computers and portable equipment
• Peripherals and modems requiring RS-232 interfaces
• Printers and instruments with limited power supplies
• Microprocessor systems needing shared data lines

Procurement Notes

Verify the specific ordering suffix matches the required package type and reel configuration. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Ensure the component version aligns with the latest datasheet revision to guarantee parameter accuracy during design validation.

Selection Notes

Select this part when a single 5 V supply is available but RS-232 voltage levels are required. The ADM206 is suitable for designs needing four drivers and three receivers with low power consumption. Consider the ADM213 if two active receivers are needed during shutdown for ring indicator monitoring. Verify thermal requirements for the SOIC package in enclosed spaces.

Part Context

The ADM206 belongs to the ADM2xx family of RS-232 transceivers designed for EIA-232-E and V.28 interfaces. This family eliminates the need for dual polarity power supplies by integrating charge pumps. The ADM206 specifically offers a configuration of four drivers and three receivers, distinguishing it from variants like the ADM207 or ADM208 which differ in driver/receiver counts or control features.

Replacement Considerations

Public confirmed substitute part numbers: ADM206AN, ADM206AR, ADM206ARS.
