MAX232ECWE+

Overview

The MAX232ECWE+ is a dual driver/receiver RS-232 transceiver designed for single +5V supply operation. It integrates charge pump circuitry to generate the required ±10V levels, eliminating the need for external bipolar power supplies. The device features high electrostatic discharge protection rated at ±15kV using the Human Body Model. It supports data rates up to 120kbps and operates within a commercial temperature range of 0°C to +70°C. The component is housed in a 16-pin Wide SOIC package.

Feature Summary

• Integrated charge pump eliminates the requirement for external bipolar voltage supplies
• High ±15kV ESD protection on all RS-232 inputs and outputs
• Single +5V power supply operation with low standby current
• Full compliance with EIA/TIA-232E and V.28 communication standards

Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools and portable instruments
• Industrial control systems exposed to harsh electrical environments

Procurement Notes

Verify the specific suffix 'CWE+' against official Analog Devices documentation to confirm the wide SOIC package and commercial temperature rating. Ensure that the ordering information matches the exact part number to avoid confusion with other variants in the MAX232 family that may have different pinouts or performance characteristics.

Selection Notes

Select this component when designing systems that require robust ESD protection for serial communication interfaces. It is suitable for applications where space constraints prevent the use of discrete level-shifting components. Confirm that the system environment remains within the specified 0°C to +70°C operating range for optimal performance.

Part Context

This device belongs to the MAX202E–MAX213E and MAX232E/MAX241E family of RS-232 transceivers manufactured by Analog Devices (formerly Maxim Integrated). The 'E' designation indicates enhanced ESD protection capabilities compared to standard versions. The MAX232 series is widely recognized for simplifying TTL/CMOS to RS-232 interface design through integrated voltage conversion.

Replacement Considerations

Direct replacements include the MAX232EESE+ and MAX232EPE+. Verify package compatibility and temperature ratings before substitution.
