MAX3232CUE+TG002

Overview

The MAX3232CUE+TG002 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 for full-duplex communication. The device utilizes a proprietary low-dropout transmitter output stage and a dual charge pump requiring only four 0.1µF external capacitors. It guarantees data rates of 120kbps with worst-case loads and typically supports up to 235kbps. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Proprietary low-dropout transmitter output stage enables true RS-232 performance from a single 3.0V to 5.5V supply.
• Dual charge pump voltage converter generates internal ±5.5V supplies using only four small 0.1µF external capacitors.
• Pin, package, and functionally compatible with industry-standard MAX242 and MAX232 devices.

Applications

• Notebook, Subnotebook, and Palmtop Computers
• High-Speed Modems
• Battery-Powered Equipment
• Hand-Held Equipment
• Peripherals

Procurement Notes

Verify the specific suffix TG002 against official manufacturer documentation to confirm tape-and-reel packaging or specific lot traceability requirements. Ensure the ordering information matches the exact temperature grade and package code listed in the datasheet to avoid functional discrepancies.

Selection Notes

Select this component when interfacing TTL/CMOS logic with RS-232 ports in portable systems requiring low power consumption. It is suitable for applications needing compatibility with standard MAX232/MAX242 footprints without redesigning the PCB layout. Verify that the required data rate does not exceed the guaranteed 120kbps or typical 235kbps limits under the specific load conditions.

Part Context

This part belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of 3V-powered RS-232 transceivers. While the MAX3232 provides a standard 2-transmitter/2-receiver configuration, other family members offer different driver counts or specialized features like MegaBaud operation or mouse driveability. This series is designed to replace older 5V-only RS-232 solutions in modern low-voltage electronics.

Replacement Considerations

The MAX3232EUE+ serves as a direct replacement offering an extended industrial temperature range (-40°C to +85°C) while maintaining identical pinouts and functionality. Other variants within the MAX32xx series may require circuit modifications due to differences in driver/receiver counts or shutdown capabilities.
