MAX3235EEWP+G36

Overview

The MAX3235EEWP+G36 is a fully compliant RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers in a single package, supporting data rates up to 250 kbps. The device operates from a single 4.5V to 5.5V supply and includes internal charge pumps to generate the required RS-232 voltage levels without external capacitors. It features 15kV ESD protection on all pins and offers a shutdown mode for low power consumption. The component is housed in a 20-SOIC surface-mount package with a width of 7.50mm.

Feature Summary

• Integrates dual drivers and dual receivers for full RS-232 communication capability within a compact footprint.
• Eliminates the need for external capacitors through built-in charge pump circuitry for voltage generation.
• Provides robust 15kV electrostatic discharge protection across all signal interfaces.
• Includes a dedicated shutdown pin to minimize current consumption during idle periods.

Applications

• Industrial control systems requiring reliable serial communication links
• Point-of-sale terminals and barcode scanners
• Modems and portable instrumentation equipment

Procurement Notes

Verify the specific suffix G36 against official manufacturer documentation to confirm RoHS compliance and lead-free status. Confirm that the EEWP variant matches the required SOIC-20 package dimensions. Check for End-of-Life notices as availability may be restricted. Ensure the ordering part number aligns with the exact temperature grade and packaging format needed for production.

Selection Notes

Select this component when designing systems requiring dual-channel RS-232 connectivity with minimal external passive components. The integrated charge pumps simplify board layout compared to older generations. Verify that the 250kbps speed meets the application's timing requirements. Consider the 0°C to 70°C operating range for environmental suitability. Compare pinout compatibility if replacing legacy transceivers in existing designs.

Part Context

This part belongs to the Maxim MAX3235E family of dual RS-232 transceivers. The family is known for combining high performance with low power consumption. The EEWP designation indicates the commercial temperature grade and specific SOIC package style. This series serves as a standard interface solution for microcontrollers needing RS-232 ports.

Replacement Considerations

Check for direct cross-references within the Maxim/Analog Devices portfolio. Verify pin-to-pin compatibility with other MAX3235 variants before substitution. Ensure any replacement maintains the same 20-SOIC package and electrical specifications.
