MAX232ACSE

Overview

The MAX232ACSE 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 with a typical quiescent current of 10mA. The device supports full-duplex communication at data rates up to 200kbps. It features two drivers and two receivers, providing TTL/CMOS-compatible inputs and outputs alongside RS-232 compliant signal levels. The component utilizes an internal charge pump circuitry to generate the necessary ±10V voltages from a single +5V supply, eliminating the need for external bipolar power sources.

Feature Summary

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

Applications

• Interface translation between TTL/CMOS logic and RS-232 serial ports
• Multidrop RS-232 network connections
• Portable diagnostic equipment utilizing standard serial communication

Procurement Notes

Verify the specific suffix 'ACSE' against the manufacturer's official ordering guide to confirm package type and temperature rating. Ensure the component matches the required industrial specifications before integration into the design.

Selection Notes

Select this component when designing systems that require standard RS-232 signaling driven by a single +5V logic supply. It is suitable for applications where board space is limited due to integrated charge pump functionality, provided the operating environment falls within the commercial temperature range.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E communications. The family offers various configurations with different numbers of drivers and receivers, catering to diverse interface requirements while maintaining compatibility with standard serial protocols.

Replacement Considerations

Direct replacements include other variants within the MAX220-MAX249 series such as the MAX232AWE or MAX232ASE, provided they match the required package and temperature specifications.
