MAX3229AEEWV+

Overview

The MAX3229AEEWV+ is a fully integrated RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +2.5V to +5.5V and features 15kV ESD protection on all RS-232 pins. The device supports data rates up to 125kbps and includes two drivers and two receivers. It is housed in a compact 30-WLP package, suitable for surface mount applications with an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• High electrostatic discharge (ESD) protection rating on all signal pins
• Low power consumption with shutdown mode capability
• Compatible with standard RS-232 voltage levels

Applications

• Mobile phone serial communication interfaces
• Personal digital assistants (PDAs)
• Handheld computing devices
• Portable medical equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variations such as cut tape versus reel quantities. Ensure the supplier provides valid traceability documentation for quality assurance purposes prior to purchase.

Selection Notes

Select this component when space-constrained designs require a complete RS-232 solution without external passive components. The WLP package offers minimal footprint compared to larger packages. Consider the 15kV ESD protection level for environments requiring robust interface durability against static discharge events.

Part Context

This part belongs to the Maxim Integrated line of low-power interface solutions designed for portable electronics. It complements other RS-232 transceivers in the portfolio that may offer different pin counts or package styles. The series focuses on reducing system cost and board area while maintaining reliable serial communication performance.

Replacement Considerations

Check for MAX3229AEEWV+T as a potential tape-and-reel variant. Verify compatibility with MAX3228EBV regarding package dimensions and electrical characteristics before substitution.
