MAX3232EEAE+T

Overview

The MAX3232EEAE+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers operating from a single +3.0V to +5.5V power supply. The device utilizes an internal dual charge pump requiring only four external 0.1μF capacitors. It supports data rates up to 250kbps with full-duplex communication. ESD protection on all pins meets ±15kV Human Body Model standards. The component operates within a temperature range of -40°C to +85°C and is housed in a 16-pin SSOP package.

Feature Summary

• Integrated dual charge pump generates required RS-232 voltage levels from a single low-voltage supply without external negative rails.
• Enhanced electrostatic discharge protection on transmitter outputs and receiver inputs ensures robustness against high-voltage static events.
• Low supply current consumption design minimizes power usage, making the device suitable for battery-operated portable systems.

Applications

• Battery-powered equipment
• Notebook, subnotebook, and palmtop computers
• Cell-phone data cables

Procurement Notes

Verify the specific ordering suffix EEAE+T corresponds to the 16-pin SSOP package and industrial temperature grade (-40°C to +85°C). Confirm lead-free status as indicated by the plus sign. Ensure compatibility with standard surface-mount assembly processes for SSOP packages.

Selection Notes

Select this component when interfacing TTL/CMOS logic with RS-232 ports in space-constrained designs. It serves as a direct pin-compatible replacement for industry-standard MAX232 devices. Verify that the application requires only two driver/receiver channels and operates within the specified 250kbps data rate limit.

Part Context

This part belongs to the MAX3222E/MAX3232E family of enhanced RS-232 transceivers. The 'E' suffix denotes the extended industrial temperature range. The 'A' indicates the specific SSOP package variant. This series provides improved ESD performance compared to legacy counterparts while maintaining functional compatibility.
