MAX232ECWE+T

Overview

The MAX232ECWE+T is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +4.5V to +5.5V supply and provides two drivers and two receivers for full-duplex communication. The device supports data rates up to 120kbps with ±15kV ESD protection (Human Body Model). It features an integrated charge pump requiring four external 1μF capacitors, eliminating the need for dual polarity supplies. The component is housed in a 16-pin Wide SO package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated high ±15kV HBM ESD protection for robust operation in harsh environments
• Single +5V supply operation enabled by internal charge-pump circuitry
• Full compliance with EIA/TIA-232E and CCITT V.28 specifications

Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Procurement Notes

Verify the specific suffix 'C' confirms the commercial temperature range (0°C to +70°C) and 'WE' indicates the 16-pin Wide SOIC package. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring single-supply RS-232 interfacing with enhanced electrostatic discharge resilience. Ensure the application environment remains within the specified 0°C to +70°C operating range. Verify that the required data rate does not exceed 120kbps under maximum load capacitance conditions.

Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. It shares architectural similarities with the standard MAX232 but includes extended ESD protection structures. The 'E' designation specifically denotes these ruggedized features compared to non-E variants.
