MAX3241EEAI+TG1Z

Overview

The MAX3241EEAI+TG1Z is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. 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 1000-4-2 Contact Discharge). The shutdown mode reduces supply current to less than 1μA, while receiver inputs remain active for monitoring.

Feature Summary

• Proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply using an internal dual charge pump.
• Enhanced electrostatic-discharge (ESD) protection protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-Gap Discharge and the Human Body Model.
• Shutdown mode significantly reduces power consumption, allowing supply current to fall below 1μA while keeping receiver inputs active for external device monitoring.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as indicated by the '+' symbol in the part number. Ensure the component matches the required pin configuration and electrical specifications for your design before procurement.

Selection Notes

Select this component when designing serial communication interfaces for portable or battery-operated systems requiring low power consumption. The integrated charge pump eliminates the need for external voltage generators, simplifying the circuit design. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This device belongs to the MAX32xxE family of RS-232 transceivers designed for space-constrained applications. It shares functional compatibility with industry-standard parts like the MAX232 but offers enhanced ESD protection and lower power consumption. The EE suffix indicates an extended industrial temperature range, while AI denotes the SSOP package.
