MAX232BAWE+T

Overview

The MAX232BAWE+T is a dual driver and receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 5V supply and includes internal charge pumps to generate the required positive and negative voltages for RS-232 signal levels, eliminating the need for external bipolar power supplies. The device supports data rates up to 120kbps and features full-duplex communication capabilities. Designed for surface-mount applications, it is housed in a 16-pin SOIC-Wide package. The component complies with RoHS standards and is intended for use in EIA/TIA-232-E and V.28/V.24 communications interface applications.

Feature Summary

• Internal charge pump circuitry generates required RS-232 voltage levels from a single 5V supply
• Supports full-duplex data transmission at rates up to 120kbps
• Eliminates the requirement for external bipolar power supplies
• Designed for compatibility with standard EIA/TIA-232-E protocols

Applications

• EIA/TIA-232-E serial communication interfaces
• V.28 and V.24 modem connections
• Industrial control system serial ports
• Embedded systems requiring RS-232 connectivity

Procurement Notes

Verify the specific suffix 'BAWE' against official Analog Devices documentation to confirm package type and temperature range. Ensure the '+T' designation matches the required reel packaging configuration for your assembly line. Cross-reference the manufacturer part number with current datasheets to validate active status and compliance certifications before procurement.

Selection Notes

Select this component when a robust, single-supply RS-232 solution is required for moderate-speed data transmission. It is suitable for designs where space constraints favor surface-mount technology over through-hole packages. Consider the 120kbps speed limit and 5V operating voltage to ensure compatibility with the target microcontroller or processor interface requirements.

Part Context

This part belongs to the Maxim MAX232 family of multichannel RS-232 drivers and receivers. The family is widely recognized for simplifying RS-232 interface design by integrating charge pumps on-chip. The MAX232 series provides a cost-effective alternative to discrete transistor solutions for standard serial communication needs in consumer and industrial electronics.

Replacement Considerations

Direct replacements include the MAX232ACWE+T and MAX232EWE+T. Verify that the replacement variant meets the specific operating temperature range and electrical specifications required by the application design.
