MAX237CWG

Overview

The MAX237CWG is a multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates five drivers and three receivers to support full-duplex communication with a data rate of 120 kb/s. The device operates on a single +5 V power supply, consuming 15 mA of current. It features a propagation delay of 10 us and lacks ESD protection or shutdown functionality. The component is housed in a 24-pin SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for multi-port serial communication
• Supports full-duplex data transmission at speeds up to 120 kb/s
• Operates exclusively on a single +5 V power supply

Applications

• Industrial control systems requiring multiple RS-232 connections
• Test and measurement equipment interfaces
• Embedded systems with serial communication requirements

Procurement Notes

Verify the specific suffix 'CWG' against official manufacturer documentation to confirm the exact temperature grade and package variant. Ensure compatibility with existing PCB footprints for the 24-SOIC package. Confirm that the absence of ESD protection meets system safety requirements without additional external components.

Selection Notes

Select this component when designing circuits requiring five transmit and three receive channels from a single IC. It is suitable for applications needing full-duplex operation at moderate speeds. Verify that the system environment remains within the specified commercial/industrial temperature limits and that the +5 V supply voltage is stable.

Part Context

This part belongs to the MAX237 series of multichannel RS-232 transceivers. It provides a compact solution for integrating multiple serial ports into a single board. The CWG suffix typically denotes a specific temperature range and package type within the Maxim Integrated product line.

Replacement Considerations

The ADM237LANZ is listed as a similar alternative. Verify pinout compatibility and electrical specifications before substitution.
