PAL20R4BMJS/883B

Programmable Logic Device Pld Overview

The PAL20R4BMJS/883B is a military-grade Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It features an OT PLD architecture with a 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 18 dedicated inputs and 4 registered outputs, configured as a combinatorial logic circuit within the specified timing constraints.

Programmable Logic Device Pld Feature Summary

• Military-grade reliability with /883B qualification suffix
• CDIP-20 metal-sealed ceramic package for harsh environments
• 18 dedicated inputs and 4 registered outputs
• 45ns maximum propagation delay

Programmable Logic Device Pld Applications

• Aerospace control systems requiring radiation-hardened or high-reliability logic
• Military communication equipment interface logic
• Industrial automation controllers operating in extreme temperature ranges

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the /883B suffix to ensure compliance with MIL-PRF-38534 standards. Confirm that the CDIP-20 package matches the specific footprint requirements of the target assembly. Check for lead integrity and seal quality due to the ceramic construction. Ensure the TTL voltage levels align with the system's power supply specifications.

Programmable Logic Device Pld Selection Notes

Select this part when registered output functionality is required alongside high-speed combinatorial logic. The 45ns delay suits applications needing moderate switching speeds. The wide temperature range (-55°C to +125°C) makes it suitable for defense and space applications where standard commercial parts would fail. Compare pinout compatibility if replacing older PAL variants.

Programmable Logic Device Pld Part Context

This component belongs to the PAL20 family of programmable logic devices from AMD. It shares architectural similarities with other PAL20 series parts but differs in output configuration and packaging. The /883B designation indicates it meets specific military performance standards, distinguishing it from commercial grade equivalents like the PAL20R4B.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other /883B qualified PAL20R4B variants from AMD or equivalent military-grade PALs from manufacturers like Lattice or National Semiconductor, provided pinouts and electrical characteristics match.
