MAX238CWG+T

Overview

The MAX238CWG+T is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features four drivers and three receivers, supporting full-duplex communication with a data rate of 120 kb/s. The device operates within a supply voltage range of 4.75 V to 5.25 V and consumes 20 mA of operating current. Packaged in a 24-pin SOIC (SOIC-24) format for surface mount installation, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates multiple drivers and receivers into a single package for compact multichannel RS-232 interface designs
• Operates exclusively on a standard +5V power supply without requiring external charge pumps or negative voltages
• Supports full-duplex data transmission at speeds up to 120 kb/s for reliable serial communication

Applications

• Industrial control systems requiring multiple serial ports
• Point-of-sale (POS) terminals with serial connectivity needs
• Medical equipment utilizing RS-232 communication protocols
• GPS navigation devices with serial data interfaces

Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through certified datasheets. Check for obsolescence notices as this component may be subject to lifecycle changes. Ensure the supplier provides traceable origin documents matching the specified part number.

Selection Notes

Select this component when designing circuits that require multiple independent RS-232 channels within a limited board area. Verify that the system power supply strictly maintains the 5V nominal requirement. Consider the 24-pin SOIC footprint constraints during PCB layout. Evaluate thermal performance if operating near the upper temperature limits.

Part Context

This part belongs to the Maxim Integrated MAX23x series of RS-232 transceivers designed for +5V operation. It shares functional similarities with other multichannel variants like the MAX239 but offers a specific driver-to-receiver ratio suited for balanced bidirectional communication needs in embedded systems.
