MAX3232ESE+T

Overview

The MAX3232ESE+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +5.5V supply and features an internal dual charge pump requiring only four 0.1µF external capacitors. The device provides full duplex communication with two drivers and two receivers, supporting data rates up to 235kbps. It is housed in a 16-pin Narrow SO package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated dual charge pump eliminates the need for bipolar ±12V supplies
• Compatible with industry-standard MAX232 pinout and functionality
• Low power consumption suitable for battery-powered applications

Applications

• Battery-powered equipment
• Hand-held devices
• Peripherals
• Datacom equipment

Procurement Notes

Verify the component against official datasheets to confirm the specific package type and temperature grade. Ensure that the ordering suffix matches the required lead-free status and packaging format. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and availability before procurement.

Selection Notes

Select this component when interfacing TTL or CMOS logic with RS-232 ports using a single voltage supply. It serves as a direct replacement for the legacy MAX232 in designs requiring lower power consumption. Verify that the application supports the guaranteed 120kbps rate or typical 235kbps performance under specified load conditions.

Part Context

This device belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of low-power RS-232 transceivers. It shares functional similarities with other members of the series but is distinct in its configuration of two drivers and two receivers. The 'E' suffix indicates the extended industrial temperature rating compared to commercial variants.
