MAX3241EEAI+

Overview

The MAX3241EEAI+T is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin SSOP package. It operates on a single +3.0V to +5.5V supply and features three drivers and five receivers. The device supports data rates up to 250kbps with typical propagation delays of 0.15µs. It incorporates an internal dual charge pump requiring four 0.1µF external capacitors. ESD protection ratings include ±15kV (Human Body Model) and ±8kV (IEC Contact Discharge). Operating temperatures range from -40°C to +85°C.

Feature Summary

• Integrated dual charge pump enables true RS-232 performance using only four small external capacitors.
• Enhanced electrostatic discharge protection safeguards all transmitter outputs and receiver inputs against high-voltage static events.
• Shutdown mode significantly reduces power consumption while maintaining active receiver monitoring capabilities.

Applications

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

Procurement Notes

Verify the specific suffix EEAI+T corresponds to the required SSOP-28 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring multiple serial ports within space-constrained mobile or notebook applications. Ensure the system voltage remains within the 3.0V to 5.5V operating range and that adequate decoupling capacitors are placed near the charge pump terminals.

Part Context

This part belongs to the MAX32xxE family of low-power RS-232 transceivers. It shares functional compatibility with industry-standard devices like the MAX232 but offers improved power efficiency and enhanced ESD robustness suitable for modern portable electronics.
