MAX237EWG+T

Overview

The MAX237EWG+T is a multichannel RS-232 transceiver manufactured by Analog Devices / Maxim Integrated. It integrates five drivers and three receivers to support 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 lacks built-in ESD protection or shutdown functionality. The component is housed in a 24-pin SOIC package and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for multi-port serial connectivity
• Supports standard RS-232 voltage levels for reliable signal transmission
• Operates efficiently on a single +5V power supply

Applications

• Industrial control systems requiring multiple serial ports
• Data acquisition equipment with RS-232 interfaces
• Communication modules for embedded systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the selected variant matches the required pinout and thermal specifications for your PCB layout. Ensure compatibility with existing design constraints regarding the absence of integrated ESD protection mechanisms.

Selection Notes

Select this component when designing circuits requiring five transmit and three receive channels within a single IC. It is suitable for applications where space efficiency is critical but external ESD protection components are preferred for higher robustness. Consider the 120 kb/s speed limit when evaluating system timing requirements.

Part Context

This part belongs to the MAX237 series of multichannel RS-232 transceivers. It shares functional similarities with other devices in the family but is distinguished by its specific count of five drivers and three receivers. The EWG+ designation confirms the industrial temperature grade and lead-free construction compliant with RoHS standards.

Replacement Considerations

Direct substitutes include the MAX237CNG+ and MAX237EWG, which offer identical electrical characteristics. Verify that any replacement maintains the same SOIC-24 footprint and driver/receiver configuration to ensure board-level compatibility.
