MAX232MLP/883B

Overview

The MAX232MLP/883B is a military-grade RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single +5V power supply and integrates charge pump circuitry to generate the required ±10V signals for EIA/TIA-232E communication without external transformers. The device features two drivers and two receivers, supporting full-duplex data transmission at rates up to 120 kbps. It is housed in a 20-pin LCC package and qualified to MIL-STD-883 standards for high-reliability applications.

Feature Summary

• Military qualification compliant with MIL-STD-883 standards for harsh environment reliability
• Integrated charge pump eliminates need for external dual-voltage power supplies or transformers
• Full-duplex operation with independent driver and receiver channels

Applications

• Military avionics communication systems requiring MIL-qualified components
• Spacecraft telemetry and command interfaces
• High-reliability industrial control networks operating in extreme temperatures

Procurement Notes

Verify that the component carries the specific /883B suffix indicating MIL-STD-883 Class B screening. Confirm lot traceability and physical inspection reports are available. Ensure the manufacturer documentation explicitly states compliance with all relevant military specifications for this exact part number before integration into certified systems.

Selection Notes

Select this variant when military qualification is mandatory rather than commercial grade. Compare propagation delay and current consumption against other MAX232 variants if system power budgets are tight. Verify that the LCC-20 package footprint matches the PCB design constraints for the target application.

Part Context

This component belongs to the MAX232 family of multi-channel RS-232 drivers and receivers. The /883B suffix distinguishes it from commercial versions by denoting adherence to strict military screening and testing protocols. It serves as a robust interface solution for legacy serial communication protocols in defense and aerospace sectors.
