MAX3232EEUP+

Overview

The MAX3232EEUP+ 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 line drivers and two line receivers with a dual charge-pump circuit requiring four external capacitors. It provides ±15kV IEC ESD protection on serial-port connection pins, including ground. The component meets TIA/EIA-232-F standards and features a 16-pin TSSOP package.

Feature Summary

• Integrates dual charge-pump circuitry for operation from a single low-voltage power supply
• Provides enhanced electrostatic discharge protection on all serial port connection pins
• Supports full-duplex communication with independent driver and receiver channels

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 exact package dimensions and material specifications. Confirm that the component version aligns with required automotive or industrial qualification standards before procurement. Ensure compatibility with existing PCB footprint designs.

Selection Notes

Select this component when designing interfaces requiring robust ESD protection and low standby current in space-constrained applications. Verify that the system voltage falls within the 3V to 5.5V operating range. Consider the 16-pin TSSOP package constraints during layout planning to ensure adequate thermal dissipation and signal integrity.

Part Context

This part belongs to the MAX3232E family of RS-232 transceivers designed for low-power, single-supply applications. It serves as a bridge between asynchronous communication controllers and serial connectors. The EE designation typically indicates extended temperature ranges and enhanced performance characteristics compared to standard commercial variants.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative offering higher speed capabilities. Verify electrical parameter compatibility and logic level thresholds when substituting components to ensure proper interface functionality.
