MAX230MJP/883B

Overview

The MAX230MJP/883B is a military-grade, multi-channel RS-232 driver manufactured by Analog Devices under the Maxim Integrated brand. It operates on a single +5V supply and integrates an internal charge pump to generate required voltage levels without external dual supplies. The device provides five drivers with no receivers, supporting data rates up to 120 kbps. It features a low-power shutdown mode consuming less than 5 µW. The component is housed in a CDIP-20 package and is rated for operation across the full military temperature range of -55°C to +125°C.

Feature Summary

• Integrates internal charge pump circuitry for single-supply operation
• Provides five independent RS-232 drivers
• Features ultra-low power consumption in shutdown mode
• Supports standard EIA/TIA-232E communication protocols

Applications

• Military communication systems requiring high reliability
• Portable diagnostic equipment with limited power resources
• Multidrop RS-232 network interfaces
• Battery-powered systems lacking dual voltage rails

Procurement Notes

Verify authenticity through authorized channels due to the component's military specification status. Confirm that the /883B suffix denotes compliance with MIL-PRF-38534 standards. Check for lot traceability and screening reports if required for mission-critical deployments. Ensure the CDIP-20 package matches the target PCB footprint exactly.

Selection Notes

Select this part when five isolated transmit channels are needed from a single +5V source. It is suitable for environments where generating negative voltages externally is impractical. Compare against receiver-integrated variants if bidirectional communication is required. Verify thermal dissipation capabilities within the specified military temperature envelope.

Part Context

This component belongs to the MAX220–MAX249 family of line drivers designed for EIA/TIA-232E interfaces. The /883B designation indicates it meets specific military reliability standards. It serves as a bridge between TTL logic levels and RS-232 signaling requirements in ruggedized electronic assemblies.

Replacement Considerations

Direct functional equivalents include other MAX230 variants such as MAX230CPE or MAX230ESE for commercial applications. For military specifications, verify cross-referencing with current MIL-PRF-38534 qualified sources.
