AD237JR

Overview

The ADM237LJRZ is a low-power RS-232 transceiver from Analog Devices, featuring five drivers and three receivers in a full-duplex configuration. It operates on a single 5 V supply with a maximum data rate of 120 kb/s and consumes 13 mA of quiescent current. The device supports the standard RS-232 protocol without shutdown functionality or integrated ESD protection. It is available in an SOIC-24 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for multi-port serial communication
• Operates on a single 5 V power supply with low 13 mA quiescent current consumption
• Supports full-duplex data transmission at rates up to 120 kb/s

Applications

• Industrial control systems requiring multiple serial ports
• Data acquisition equipment with RS-232 connectivity
• Embedded systems needing high-density serial interfaces

Procurement Notes

Verify the exact part number suffix, as the provided model AD237JR differs from the documented ADM237LJRZ. Confirm package type availability, as the verified document specifies SOIC-24. Check regional sales restrictions and lead times directly with the manufacturer or authorized distributors, as local stock may be limited.

Selection Notes

Select this component when designing systems requiring five transmit and three receive channels on a single chip. Ensure the application does not require shutdown modes or built-in ESD protection, as these features are absent. Verify that the 120 kb/s speed limit meets system requirements and that the operating voltage aligns with the 5 V rail.

Part Context

This component belongs to the ADM237L series of RS-232 interface ICs manufactured by Analog Devices. It is designed for applications needing multiple serial lines without the complexity of external multiplexing. The series focuses on low power consumption and reliable operation in industrial environments.
