AD234JN

Overview

The AD234JN is a monolithic CMOS integrated circuit containing four RS-232 drivers and receivers, designed for operation from a single 5 V power supply. It features internal charge pumps that generate the required positive and negative voltages for RS-232 signal levels, eliminating the need for external dual supplies. The device complies with EIA/TIA-232-F and ITU-T V.28 standards, providing full driver and receiver functionality in a compact package suitable for serial communication applications.

Feature Summary

• Single 5 V power supply operation
• Internal charge pump voltage generation
• Full compliance with RS-232 standards

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered instruments
• Modem interfaces and data transmission equipment

Procurement Notes

Verify the specific suffix 'JN' corresponds to the plastic DIP package variant when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or its subsidiary ADI. Ensure the component meets the required environmental specifications for the intended deployment environment.

Selection Notes

Select this component when a single-supply solution is required for RS-232 interfacing without external inductors. Consider the package type and temperature range requirements relative to the system constraints. Evaluate pin compatibility if replacing legacy components in existing designs.

Part Context

This part belongs to the family of 5 V powered CMOS RS-232 transceivers manufactured by Analog Devices. These devices are engineered to simplify serial port implementation by integrating the necessary voltage conversion circuitry on-chip, reducing board space and component count compared to older bipolar solutions.
