MAX3232EEAE+G1Z

Overview

The MAX3232EEAE+G1Z is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and provides two drivers and two receivers for full-duplex communication. The device incorporates a dual charge-pump circuit requiring four external 0.1µF capacitors. It supports data rates up to 250kbit/s with a maximum driver output slew rate of 30V/µs. The component features ±15kV IEC ESD protection on serial-port connection pins, including ground. It is housed in a 16-pin SSOP package (0.209" width) and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides electrical interface between asynchronous controllers and serial connectors via TIA/EIA-232-F compliance
• Integrates dual charge-pump circuitry for voltage generation from a single low-voltage supply
• Includes robust ±15kV IEC ESD protection on all serial port pins

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems
• Battery-powered portable devices

Procurement Notes

Verify the specific suffix G1Z against current manufacturer documentation to confirm lead-free status and environmental compliance. Confirm package dimensions match the 16-SSOP specification. Check for obsolescence notices or lifecycle changes as this component may be subject to discontinuation. Ensure supplier sources are authorized to guarantee authenticity.

Selection Notes

Select this component when designing systems requiring RS-232 connectivity with integrated ESD protection. Verify that the application environment falls within the -40°C to +85°C operating range. Ensure the power supply remains stable between 3V and 5.5V. Confirm that the 250kbit/s data rate meets system timing requirements.

Part Context

This part belongs to the MAX3232E series of true RS-232 transceivers. It shares functional similarities with other members of the family but differs in packaging and specific environmental ratings. The EE designation typically indicates extended temperature ranges compared to standard commercial variants.

Replacement Considerations

SNx5C3232 is identified as a pin-compatible alternative high-speed device offering 1Mbit/s operation.
