MAX237MRG

Overview

The MAX237MRG is a multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V power supply and integrates five drivers and three receivers for full-duplex communication. The device supports data rates up to 120 kb/s with a propagation delay of 10 µs. It draws 15 mA of operating current and functions within a temperature range of -40°C to +85°C. The component is housed in a 24-pin SOIC package designed for surface mount installation.

Feature Summary

• Integrates multiple driver and receiver channels for complex serial interface requirements
• Operates exclusively from a single +5V power source without requiring negative voltages
• Supports full-duplex data transmission at standard RS-232 speeds

Applications

• Industrial control systems requiring multi-port serial connectivity
• Communication equipment utilizing RS-232 standards
• Embedded systems needing compact multichannel interface solutions

Procurement Notes

Verify the specific suffix MRG against official datasheets to confirm the SOIC-24 package configuration. Ensure compatibility with the required operating temperature range and voltage specifications before integration into the design.

Selection Notes

Select this component when designing circuits that require more than two RS-232 channels on a single chip. Confirm that the system operates strictly at +5V, as the device lacks internal charge pumps for generating negative voltages from other supply rails.

Part Context

This part belongs to the MAX237 series of multichannel RS-232 transceivers. It provides a consolidated solution for applications requiring multiple serial ports, reducing board space compared to using individual dual-channel transceivers.

Replacement Considerations

Check for updated versions or pin-compatible alternatives within the MAX23x family if availability is constrained. Verify that any substitute maintains the same channel count and package dimensions.
