AD238AR

Overview

The AD238AR is a CMOS RS-232 line transceiver designed for EIA-232-E and V.28 communication interfaces. It integrates four drivers and four receivers powered by a single +5 V supply, utilizing onboard DC-DC converters to generate required voltage levels without external components. The device supports data rates up to 120 kB/s and operates within a temperature range of -40 °C to +85 °C.

Feature Summary

Integrates four drivers and four receivers in a single package
Operates from a single +5 V power supply
Includes onboard DC-DC converters eliminating external capacitors
Meets EIA-232-E and V.28 interface specifications

Applications

Computer serial port implementations
Peripheral connectivity systems
Modem interface circuits
Industrial instrument communication

Procurement Notes

Verify the specific suffix 'AR' against official Analog Devices documentation to confirm exact packaging type and commercial availability status. Ensure compliance with RoHS directives as indicated by the manufacturer's current product classification. Cross-reference the part number with authorized distributors to validate authenticity and sourcing channels.

Selection Notes

Select this component for applications requiring full-duplex RS-232 communication without access to dual polarity power supplies. The integrated charge pump simplifies PCB layout by removing external boost capacitors. Consider the 120 kB/s speed limit when designing for high-throughput serial links or longer cable runs requiring signal integrity optimization.

Part Context

This device belongs to the AD2xx family of CMOS RS-232 transceivers manufactured by Analog Devices. It serves as a legacy interface solution for standard serial communications, offering a robust alternative to older bipolar technologies while maintaining compatibility with established EIA standards for industrial and commercial equipment.

Replacement Considerations

The ADM238LAN is documented as a plug-in upgrade for the AD238 series. Verify pinout compatibility and electrical parameter equivalence before substitution. Other members of the ADM2xx family may offer similar functionality but require individual datasheet comparison for feature alignment.
