MAX232AESE+

Overview

The MAX232AESE+ is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V with a typical operating current of 10 mA. The device supports full-duplex communication at data rates up to 200 kb/s. It features two drivers and two receivers housed in a 16-pin SO-Narrow package. The component functions across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar ±12V supplies, enabling single +5V operation.
• Provides full-duplex RS-232 signal translation between TTL/CMOS logic levels and EIA/TIA-232E standards.
• Designed for applications where printed circuit board space is critical due to compact packaging.

Applications

• Interface Translation
• Multidrop RS-232 Networks
• Portable Diagnostics Equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer certificates. Ensure the source document matches the exact part number to avoid discrepancies in electrical characteristics or pin configurations.

Selection Notes

Select this component when designing systems requiring RS-232 communication powered exclusively by a single +5V supply. Verify that the required data rate does not exceed 200 kb/s under the intended load conditions. Ensure the application environment falls within the specified -40°C to +85°C operating temperature range.

Part Context

This component belongs to the MAX220–MAX249 family of line drivers and receivers. The 'A' designation indicates an advanced version optimized for lower power consumption compared to standard variants. The 'E' suffix specifies the industrial temperature range, while 'SE' denotes the 16-pin Narrow SOIC package format.

Replacement Considerations

The MAX232EESE+ serves as a verified alternative within the same product family. Both parts share identical pinouts and core functionality but may differ in specific manufacturing revisions or minor electrical tolerances defined in their respective datasheets.
