MAX3241EEUI+G1Z

Overview

The MAX3241EEUI+G1Z is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin TSSOP package. It operates on a single +3.0V to +5.5V supply and features three drivers and five receivers for full-duplex communication. The device guarantees data rates up to 250kbps at standard loads and up to 1Mbps under specific conditions. It incorporates an internal dual charge pump requiring only four 0.1µF external capacitors. Supply current is typically 1mA, dropping to less than 1µA in shutdown mode. ESD protection is rated at ±15kV (Human Body Model) and ±8kV (IEC Contact Discharge).

Feature Summary

• Integrated dual charge pump enables operation from a single low-voltage supply using minimal external capacitance.
• 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 component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required temperature range and packaging specifications. Ensure compliance with relevant environmental directives such as RoHS before integration into production systems.

Selection Notes

Select this component when designing serial communication interfaces for space-constrained mobile devices. It is suitable for applications requiring low-power standby modes and robust signal integrity over standard RS-232 lines without external voltage generation circuits.

Part Context

This part belongs to the MAX32xxE family of low-power RS-232 transceivers. It shares functional compatibility with industry-standard parts like the MAX232 but offers improved power efficiency and higher ESD tolerance. The EE suffix indicates an extended industrial temperature range compared to commercial variants.

Replacement Considerations

MAX3241EUI+ serves as a direct pin-compatible alternative within the same product family. Verify that the replacement maintains the required operating temperature range and package dimensions for the target application.
