ADM223ARS

Overview

The ADM223ARS is a CMOS RS-232 transceiver manufactured by Analog Devices Inc., designed for operation with a single 5 V power supply. It integrates two drivers and two receivers, supporting full-duplex communication at data rates up to 120 kb/s. The device utilizes external 0.1 µF capacitors for charge pumping, eliminating the need for dual voltage supplies. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 16-pin SOIC package.

Feature Summary

• CMOS technology enables low power consumption while maintaining high noise immunity
• Single 5 V supply operation simplifies system design by removing the requirement for negative voltage rails
• Integrated charge pump circuitry generates required internal voltages using small external capacitors

Applications

• Industrial control systems requiring robust serial communication
• Embedded systems with limited power supply options
• Data acquisition equipment interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'ARS' corresponds to the 16-pin SOIC package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the component matches the exact part number to avoid functional discrepancies related to packaging or temperature ratings.

Selection Notes

Select this component for applications requiring standard RS-232 signaling with minimal external passive components. It is suitable for designs constrained by space due to its integrated charge pump. Consider alternative ESD-protected variants if the application environment demands higher electrostatic discharge immunity than the standard ADM223 series provides.

Part Context

The ADM223 belongs to Analog Devices' family of 5 V powered CMOS RS-232 drivers and receivers. This series is characterized by its ability to operate from a single supply voltage, reducing system complexity compared to older bipolar RS-232 transceivers that required dual positive and negative supplies.

Replacement Considerations

ADM223ARZ: Identical electrical specifications with different packaging suffix indicating tape and reel availability.
