MAX3232EEWE+TG1Z

Overview

The MAX3232EEWE+TG1Z is an automotive-grade RS-232 transceiver designed for reliable serial communication in demanding environments. It integrates two line drivers and two receivers with a dual charge-pump circuit, enabling operation from a single 3V to 5.5V supply without external negative voltage sources. The device supports data rates up to 250kbit/s and features ±15kV IEC ESD protection on all serial-port connection pins. Qualified for automotive applications, it meets TIA/EIA-232-F standards and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Automotive qualification ensuring compliance with rigorous reliability standards
• Integrated dual charge pump eliminates the need for external negative power supplies
• Robust ±15kV IEC electrostatic discharge protection across all interface pins

Applications

• Industrial PCs requiring robust serial connectivity
• Wired networking equipment interfaces
• Battery-powered portable systems

Procurement Notes

Verify that the specific suffix indicates automotive grade (AEC-Q100) and package type (SOIC-16). Confirm RoHS compliance status and check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when automotive environmental resilience and high ESD immunity are required for RS-232 links. Ensure the design accommodates four external capacitors for the charge pump. Verify that the 250kbit/s speed meets system timing requirements compared to higher-speed alternatives.

Part Context

This part belongs to the MAX3232E family of low-power RS-232 transceivers. The 'EE' designation typically denotes extended industrial/automotive temperature ranges and enhanced ESD protection compared to standard commercial variants. The '+T' suffix indicates tape-and-reel packaging for automated assembly.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative offering higher speeds up to 1Mbit/s. Verify compatibility with existing PCB layouts and capacitor values when considering substitution.
