MAX202ECWE+T

Drivers, Receivers, Transceivers Overview

The MAX202ECWE+T is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers operating in full-duplex mode, supporting data rates up to 120kbps. The device operates on a single +4.5V to +5.5V supply voltage and utilizes an internal charge pump to generate the required ±10V levels for RS-232 signaling. It includes integrated high ±15kV HBM ESD protection on all pins. The component is housed in a 16-pin Wide SOIC package and is rated for an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar power supplies, enabling operation from a single +5V source.
• Provides robust electrostatic discharge protection with ±15kV Human Body Model ratings on driver outputs and receiver inputs.
• Drivers and receivers meet EIA/TIA-232E and CCITT V.28 specifications at data rates up to 120kbps under standard loading conditions.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools and portable instrumentation
• Portable computers and notebook interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CWE+T' against official documentation to confirm the wide SOIC package, commercial temperature range, and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints for 16-pin wide SOIC components. Confirm RoHS compliance status through manufacturer certificates prior to integration into production assemblies.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require RS-232 connectivity without generating negative voltages externally. It is suitable for applications needing moderate data rates up to 120kbps. Consider the commercial temperature range limits if the environment exceeds 70°C. Verify that the 0.1μF external capacitors required for the charge pump fit within the board space constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers designed for single-supply operation. The 'E' designation indicates enhanced ESD protection compared to standard versions. The 'C' suffix denotes the commercial temperature range, while 'W' specifies the wide SOIC package type. This family allows direct interface between TTL/CMOS logic devices and RS-232 ports.
