MAX3241ECAI+T

Overview

The MAX3241ECAI+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 guarantees data rates up to 250kbps with worst-case loads of 3kΩ in parallel with 1000pF. It incorporates an internal dual charge pump requiring only four 0.1μF external capacitors. ESD protection is rated at ±15kV (Human Body Model) and ±8kV (IEC Contact Discharge). Operating temperature range is -40°C to +85°C.

Feature Summary

• Integrated dual charge pump enables true RS-232 performance from a single low-voltage supply using minimal external components.
• Enhanced electrostatic discharge protection safeguards 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 'EAI' corresponds to the required industrial temperature range (-40°C to +85°C) and SSOP-28 packaging configuration. Confirm RoHS compliance status for the '+T' reel packaging variant before finalizing procurement specifications.

Selection Notes

Select this component when designing serial communication interfaces for space-constrained mobile devices requiring low-power operation. Ensure the application supports the necessary four 0.1μF external capacitors for the internal charge pump circuitry.

Part Context

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