MAX237CWG+

Overview

The MAX237CWG+ is a multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates five drivers and three receivers within a single SOIC-24 package, supporting full-duplex communication at data rates up to 120 kb/s. The device operates on a single +5 V power supply with a typical operating current of 15 mA. It features a propagation delay of 10 µs and functions reliably across an industrial temperature range from -40°C to +85°C. This component lacks ESD protection and shutdown capabilities, serving as a dedicated interface solution for serial communication applications.

Feature Summary

• Integrates five independent drivers and three receivers for complex multi-port RS-232 connectivity
• Supports full-duplex data transmission at speeds up to 120 kb/s
• Operates exclusively on a single +5 V power supply rail

Applications

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

Procurement Notes

Verify the specific suffix 'CWG+' against official Analog Devices documentation to confirm the commercial grade and tube packaging format. Ensure compatibility with existing board layouts designed for SOIC-24 footprints. Cross-reference the part number with current manufacturer lifecycle status to avoid obsolescence risks during production planning.

Selection Notes

Select this component when five transmit and three receive channels are required in a compact surface-mount package. It is suitable for designs constrained to a single +5 V supply without needing low-power shutdown modes. Consider alternative parts if ESD protection or higher data rates are mandatory for the target application environment.

Part Context

This part belongs to the MAX237 series of multichannel RS-232 transceivers. It shares functional similarities with other members like the MAX237CNG+ but differs in package type and temperature rating. The CWG+ designation specifically indicates the commercial temperature range and SOIC-24 surface-mount configuration.
