MAX236EWG-T

Overview

The MAX236EWG-T is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates five drivers and three receivers within a single SOIC-24 package to support full-duplex communication at data rates up to 120 kb/s. The device operates on a single 5 V supply with a typical operating current of 15 mA. It functions across an industrial temperature range from -40°C to +85°C. The component lacks ESD protection features and does not include a shutdown mode. Propagation delay is specified at 10 µs.

Feature Summary

• Integrates five independent line drivers and three receivers for high-density serial communication interfaces
• Operates exclusively on a single +5 V power supply without requiring external negative voltage generation
• Supports standard EIA/TIA-232E and V.28/V.24 protocols for reliable data transmission

Applications

• Industrial control systems requiring multiple serial ports
• Data acquisition equipment with limited power supply options
• Embedded communication modules in harsh environments

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm that the part number corresponds to the exact driver and receiver count required for the design. Ensure the absence of ESD protection aligns with system-level safety requirements. Check for RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require five transmit channels and three receive channels on a single IC. It is suitable for applications where space constraints favor a 24-pin SOIC package over larger footprints. Consider the lack of shutdown functionality if power management during idle states is critical to the system architecture.

Part Context

This device belongs to the MAX220–MAX249 family of multichannel RS-232 drivers and receivers. These components are designed to replace traditional dual-chip solutions by integrating charge pumps internally. The family provides a compact alternative for systems needing multiple serial interfaces without the complexity of generating internal negative voltages externally.

Replacement Considerations

The MAX237EWG+ serves as a functional substitute within the same product family. Both devices share identical pinouts and electrical characteristics, differing primarily in the specific configuration of drivers and receivers integrated into the silicon.
