MAX237CWG+T

Overview

The MAX237CWG+T is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates five drivers and three receivers in a single SOIC-24 package, supporting full-duplex communication at data rates up to 120 kb/s. The device operates with a fixed 5 V supply voltage and draws 15 mA of operating current. It lacks shutdown functionality and does not include built-in ESD protection. The component functions within a commercial temperature range of 0°C to +70°C and exhibits a propagation delay of 10 µs.

Feature Summary

• Integrates five drivers and three receivers for multichannel serial communication
• Operates directly from a single +5 V power supply without external charge pumps
• Supports full-duplex data transmission at speeds up to 120 kb/s

Applications

• Industrial control systems requiring multiple RS-232 connections
• Test and measurement equipment interfaces
• Multichannel data acquisition systems

Procurement Notes

Verify the specific suffix CWG+T against official datasheets to confirm the SOIC-24 package and lead-free status. Confirm that the absence of ESD protection meets system requirements. Ensure the 120 kb/s speed limit aligns with application needs. Validate the commercial temperature range suitability for the intended environment.

Selection Notes

Select this component when multiple RS-232 channels are needed on a single +5 V rail. It suits designs where space efficiency outweighs the need for high-speed or low-power operation. Consider alternatives if ESD protection or shutdown modes are required. Verify compatibility with existing logic levels and interface protocols.

Part Context

This part belongs to the MAX237 series of multichannel RS-232 transceivers. It shares the core architecture with variants like MAX237EWG+, differing primarily in package type and temperature rating. The CWG suffix denotes the plastic SOIC-24 package suitable for surface mount applications.

Replacement Considerations

Direct substitutes include MAX237EWG+ and MAX237CNG+. Verify pinout compatibility and ensure the replacement matches the required temperature range and package dimensions.
