MAX3232EEAE+

Overview

The MAX3232EEAE+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and supports data rates up to 250kbit/s. The device integrates two drivers and two receivers with ±15kV IEC ESD protection on serial-port connection pins. It requires four external 0.1μF capacitors for the charge pump circuit. The component is housed in a 16-pin SSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual line drivers and receivers for full-duplex communication
• Provides ±15kV IEC ESD protection on signal and ground pins
• Operates from a single 3V to 5.5V power supply
• Accepts 5V logic inputs while powered by a 3.3V supply

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature grade, and environmental compliance status. Confirm current production status and availability through authorized distributors, as product lifecycles may change. Ensure the selected variant matches the required interface voltage levels and ESD protection specifications for the target application environment.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with robust ESD protection. Verify that the system design accommodates the necessary four external capacitors for the internal charge pump. Ensure the operating voltage range aligns with the available power supply rails and that the thermal characteristics are suitable for the intended enclosure constraints.

Part Context

This part belongs to the MAX3232E series of low-power RS-232 transceivers. It provides pin-compatible alternatives for higher-speed applications, such as the SNx5C3232. The device is designed to meet TIA/EIA-232-F standards, serving as a bridge between asynchronous controllers and serial connectors in various computing and industrial environments.

Replacement Considerations

Check for direct pin-compatible replacements like the SNx5C3232 if higher data rates are needed. Verify equivalent RoHS compliance and lead finish options when sourcing substitutes. Ensure any alternative maintains the same 16-pin SSOP footprint and electrical interface requirements.
