MAX3232EEUP+T

Overview

The MAX3232EEUP+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers with ±15kV IEC ESD protection on all serial-port connection pins, including ground. The device operates from a single 3V to 5.5V supply and utilizes an internal dual charge-pump circuit requiring only four small external capacitors. It supports data signaling rates up to 250kbit/s and meets TIA/EIA-232-F standards. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Integrated dual charge-pump circuit enables operation from a single power supply without negative voltage rails.
• Provides robust electrostatic discharge protection exceeding ±15kV IEC standards across all interface pins.
• Maintains full compatibility with industry-standard pinouts and functionality of legacy RS-232 devices.

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems

Procurement Notes

Verify the specific suffix 'EUP' against official manufacturer documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the ordering information matches the current datasheet revision to avoid discrepancies in lead finish or moisture sensitivity levels.

Selection Notes

Select this component for designs requiring standard RS-232 communication with minimal external passive components. It is suitable for applications where space constraints favor surface-mount packaging and where moderate data rates are sufficient. Confirm that the operating temperature range aligns with the system environment requirements.

Part Context

This part belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a direct replacement for older generations like the MAX232 while offering improved power efficiency and enhanced ESD protection capabilities. The device bridges the gap between microcontroller logic levels and standard serial port connectors.

Replacement Considerations

The SNx5C3232 series offers pin-compatible alternatives with higher data rate capabilities up to 1Mbit/s. Verify signal integrity requirements before substituting, as the original device is optimized for speeds up to 250kbit/s.
