MAX3232EEAE

Overview

The MAX3232EEAE+ is a dual driver/receiver RS-232 transceiver manufactured by Analog Devices/Maxim Integrated. It operates on a single 3V to 5.5V supply and supports data rates up to 1Mbps. The device features ±15kV ESD protection, low standby current down to 10nA, and requires only four external capacitors for charge pump operation. It is housed in an SSOP-16 package.

Feature Summary

• Integrated dual charge pump circuit enabling true RS-232 performance from a single low-voltage power supply without requiring negative voltage rails.
• Robust electrostatic discharge protection rated at ±15kV across all serial port connection pins, including ground, ensuring reliability in high-interference environments.
• Ultra-low power consumption with standby current as low as 10nA, designed to extend battery life in portable and handheld computing applications.

Applications

• Battery-powered systems such as PDAs and notebooks
• Industrial PCs and wired networking equipment
• Data center and enterprise computing infrastructure

Procurement Notes

Verify the specific suffix 'EAE+' against the manufacturer's official ordering guide to confirm the exact package type (SSOP) and temperature range. Ensure compatibility with your PCB footprint dimensions and soldering profile requirements before finalizing procurement orders.

Selection Notes

Select this component when designing for space-constrained portable devices requiring robust ESD protection and minimal quiescent current. Verify that the required data rate does not exceed 1Mbps and that the system operates within the specified 3V to 5.5V supply voltage range for optimal signal integrity.

Part Context

This part belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a bridge between asynchronous communication controllers and serial-port connectors, widely used in legacy serial interface designs where reliable data transmission over short distances is critical.

Replacement Considerations

Public confirmed substitute part numbers include SNx5C3232 variants for higher speed requirements. Verify pinout compatibility and electrical specifications before substitution.
