MAX3232ECTE+

Overview

The MAX3232ECTE+ is an automotive-grade RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers with ±15kV IEC ESD protection, operating on a single 3V to 5.5V supply. The device supports data rates up to 250kbit/s and includes a dual charge pump requiring four external capacitors. Qualified for automotive applications, it meets TIA/EIA-232-F standards and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Integrated ±15kV IEC electrostatic discharge protection on all serial port pins
• Dual charge pump architecture enabling operation from a single low-voltage supply
• Full duplex communication capability with independent driver and receiver channels

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems
• Battery-powered portable devices

Procurement Notes

Verify the specific suffix 'ECTE+' against official manufacturer documentation to confirm package type and material composition. Ensure the component matches the intended automotive grade requirements. Cross-reference the ordering information with current datasheets to validate availability and compliance status before procurement.

Selection Notes

Select this component when automotive reliability and high ESD immunity are required for RS-232 interfaces. It is suitable for designs needing full-duplex communication without negative voltage supplies. Consider the 250kbit/s speed limit and 16-pin TSSOP footprint during PCB layout planning.

Part Context

This part belongs to the MAX3232E family of multichannel RS-232 line drivers and receivers. It shares functional compatibility with standard catalog versions but includes enhanced automotive qualification. The device provides a robust interface between asynchronous controllers and serial connectors in demanding environments.

Replacement Considerations

Pin-compatible alternatives include the SNx5C3232 series for higher speed requirements up to 1Mbit/s. Verify that any substitute maintains the same automotive qualification level and ESD protection specifications.
