MAX232BEAWE+

Overview

The MAX232BEAWE+ 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 4.5V to 5.5V and supports data rates up to 200kbps. The device features two drivers and two receivers with full-duplex communication capabilities. It utilizes an integrated charge pump circuitry to generate the required ±10V levels from a single +5V supply, eliminating the need for external bipolar supplies. The component is housed in a 16-pin Wide SOIC package and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar power sources.
• Provides full-duplex RS-232 communication through dual drivers and dual receivers.
• Designed for EIA/TIA-232E and V.28/V.24 interface compatibility.

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostics equipment

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated in current datasheets. Ensure the component matches the exact part number to avoid functional discrepancies related to pinouts or electrical characteristics.

Selection Notes

Select this component when designing systems that require RS-232 connectivity powered solely by a +5V rail. It is suitable for applications where board space is limited due to the integration of charge pump capacitors. Verify that the required data rate does not exceed 200kbps and that the operating environment falls within the specified temperature range.

Part Context

This component belongs to the MAX220–MAX249 family of line drivers and receivers. This series is specifically engineered for communications interfaces where generating ±12V or ±15V supplies is impractical. The family offers various configurations to accommodate different numbers of drivers and receivers across multiple package options.

Replacement Considerations

Compatible substitutes include other members of the MAX220–MAX249 family such as the MAX232CWE+ or MAX232EESE+. When replacing, ensure the alternative part maintains the same 16-pin Wide SOIC footprint and meets the required -40°C to +85°C temperature specifications.
