PAL20R8BMJS/883B

Programmable Logic Device Pld Overview

The PAL20R8BMJS/883B is a military-grade Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It features an OT PLD architecture with a maximum propagation delay of 45ns and TTL input compatibility. The component utilizes a CDIP-20 ceramic dual in-line package, rated for operation between -55°C and +125°C. It provides 16 dedicated inputs and 8 registered outputs, supporting complex sequential logic applications in high-reliability environments.

Programmable Logic Device Pld Feature Summary

• Military-grade reliability via MIL-STD-883 B-class certification
• CDIP-20 ceramic package for harsh environment durability
• Registered output architecture with 16 inputs and 8 outputs
• TTL-compatible logic levels

Programmable Logic Device Pld Applications

• Aerospace control systems
• Military communication equipment
• High-reliability industrial automation

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the AMD manufacturer marking and the specific 883B qualification suffix. Confirm the physical integrity of the ceramic DIP housing and lead frames. Ensure the component meets current environmental compliance requirements for restricted substances if applicable to the end-use system.

Programmable Logic Device Pld Selection Notes

Select this part when a registered PAL solution with military temperature range and radiation hardness is required. Compare against standard commercial PAL20R8 variants if cost reduction is prioritized over extreme environmental tolerance. Verify pinout compatibility with existing PCB footprints designed for 20-pin DIP packages.

Programmable Logic Device Pld Part Context

This component belongs to the PAL20R8 family of programmable logic devices. The 'MJ' suffix indicates the metal-sealed ceramic DIP package, while '/883B' denotes compliance with MIL-STD-883 Class B standards. It serves as a direct replacement for older discrete TTL logic circuits in legacy military designs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other qualified PAL20R8 variants from AMD or third-party manufacturers offering MIL-STD-883 certified equivalents. Ensure the substitute maintains the same registered output configuration and timing characteristics.
