MAX3232EEUP

Overview

The MAX3232EEUP is a multichannel RS-232 line driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and supports data rates up to 250kbit/s. The device integrates two drivers and two receivers with ±15kV IEC ESD protection on all serial-port connection pins, including ground. It utilizes a dual charge-pump circuit requiring four external 0.1μF capacitors to generate the necessary voltage levels for true RS-232 performance. The component is housed in a 16-pin TSSOP (PW) package.

Feature Summary

• Integrates dual charge-pump circuitry to enable true RS-232 signaling using only a single low-voltage power supply.
• Provides comprehensive pin-to-pin electrostatic discharge protection rated at ±15kV IEC standards across all serial interface connections.
• Maintains compatibility with industry-standard MAX232 pinouts while supporting logic inputs compatible with both 3.3V and 5V systems.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required automotive qualification level or standard catalog status. Confirm the package type corresponds to the TSSOP-16 designation. Ensure the supplier provides traceability documentation consistent with the manufacturer's quality guidelines. Cross-reference the part marking against official datasheet images to validate authenticity before integration into production designs.

Selection Notes

Select this component when designing interfaces between asynchronous communication controllers and serial connectors requiring robust ESD resilience. It is suitable for applications operating within the -40°C to +85°C temperature range. Consider alternative high-speed pin-compatible devices if data rates exceeding 250kbit/s are required. Verify capacitor values align with the specific VCC supply voltage used in the target design.

Part Context

This device belongs to the MAX3232 family of RS-232 transceivers designed for low-power, single-supply operation. It serves as a bridge between TTL/CMOS logic levels and standard RS-232 voltage swings. The EEUP variant specifically denotes the extended industrial temperature range and the TSSOP surface-mount packaging format, distinguishing it from other package options within the same functional family.

Replacement Considerations

The SNx5C3232 series offers a pin-compatible alternative with higher data rate capabilities up to 1Mbit/s. Catalog versions such as MAX3232E provide equivalent functionality without automotive qualification requirements.
