MAX3232ECAE+T

Overview

The MAX3232ECAE+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +5.5V supply and features two drivers and two receivers. The device guarantees data rates up to 250kbps while maintaining standard RS-232 output levels. It incorporates an internal dual charge pump requiring only four 0.1μF external capacitors. Enhanced ESD protection provides ±15kV Human Body Model tolerance on all pins. The component is housed in a 16-pin SSOP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated dual charge pump enables operation from a single low-voltage supply without external voltage inversion circuits.
• Enhanced electrostatic discharge protection safeguards transmitter outputs and receiver inputs against high-voltage static events.
• Low-dropout transmitter stage ensures compliance with EIA/TIA-232 voltage standards across the full supply voltage range.
• Pin, package, and functional compatibility with industry-standard MAX232 devices facilitates direct upgrades.

Applications

• Battery-powered portable equipment
• Cell phone and smart phone data cables
• Notebook and subnotebook computers

Procurement Notes

Verify the specific suffix 'AE' corresponds to the 16-pin SSOP package and the 'C' grade indicates the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure ordering details match the exact part number to avoid pinout or performance discrepancies.

Selection Notes

Select this component for designs requiring a drop-in replacement for legacy MAX232 systems operating at 3V to 5.5V. It is suitable for applications needing enhanced ESD robustness without adding discrete protection components. Consider the 16-pin SSOP footprint when finalizing PCB layout constraints.

Part Context

This device belongs to the MAX32xxE family of True RS-232 Transceivers. The 'E' suffix denotes enhanced ESD protection capabilities compared to standard variants. The MAX3232 variant specifically provides a complete serial port solution with two drivers and two receivers, distinct from single-driver or multi-driver models within the same datasheet.

Replacement Considerations

The MAX3232CAE+T serves as a compatible alternative but lacks the enhanced ESD protection specified for the 'E' series. Verify that the reduced ESD rating meets the environmental requirements of the target application before substitution.
