MAX232MJE/883B

Overview

The MAX232MJE/883B is a dual driver and dual receiver RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for MIL-STD-883 compliance. It operates from a single 5V supply and includes on-chip charge pumps to generate V+ and V- voltages for RS-232 signal levels. The device features low supply current consumption and supports data rates up to 120 kbps. It is housed in a CDIP-16 package suitable for through-hole mounting.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors typically required for voltage generation.
• Compliant with MIL-STD-883 standards for military-grade reliability and performance.
• Operates efficiently from a single 5V power supply source.

Applications

• Military communication systems requiring robust serial interface connectivity.
• Avionics equipment utilizing RS-232 protocols for data transmission.
• Industrial control systems operating in harsh environmental conditions.

Procurement Notes

Verify authenticity through authorized distributors or direct manufacturer channels due to the component's military specification status. Request full traceability documentation including lot codes and test reports. Confirm that the part number suffix matches the exact variant required for your specific application constraints. Ensure handling procedures comply with electrostatic discharge protection guidelines during installation.

Selection Notes

Select this component when MIL-STD-883 qualification is mandatory for the system design. Compare pin compatibility with standard commercial MAX232 variants if space constraints allow for alternative packages. Evaluate thermal requirements as the CDIP package offers different dissipation characteristics compared to surface-mount options. Ensure the single 5V supply capability aligns with the available power rails in the target hardware architecture.

Part Context

This part belongs to the MAX232 family of RS-232 transceivers, widely recognized for enabling communication between microprocessors and standard serial ports. The /883B suffix indicates adherence to strict military quality standards, distinguishing it from commercial grade counterparts. It serves as a bridge between TTL logic levels and RS-232 voltage specifications within high-reliability electronic assemblies.
