PAL20R8AML/883B

Programmable Logic Device Pld Overview

The PAL20R8AML/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 logic compatibility. The component utilizes a CDIP-20 ceramic dual in-line package, rated for operation between -55°C and +125°C. It provides 20 dedicated inputs and 8 registered outputs, supporting combinatorial output functions within a metal-sealed cofired ceramic body.

Programmable Logic Device Pld Feature Summary

• Military-grade reliability with /883B certification suffix
• CDIP-20 metal-sealed ceramic package for harsh environments
• 45ns propagation delay with TTL input compatibility
• 20 dedicated inputs and 8 registered outputs

Programmable Logic Device Pld Applications

• High-reliability aerospace control systems
• Military communication interface logic
• Harsh environment industrial automation controllers

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 for the target assembly. Check for lead integrity and ceramic seal quality due to the military specification nature of the component.

Programmable Logic Device Pld Selection Notes

Select this part when registered I/O functionality is required in a high-speed TTL environment. The 20-input capacity suits complex decoding or state machine implementations. Ensure the design accommodates the thermal characteristics of the ceramic DIP package and the 5V supply voltage typical of TTL logic families.

Programmable Logic Device Pld Part Context

This component belongs to the PAL20R series of programmable array logic devices from AMD. It serves as a fixed-function replacement for discrete logic gates in legacy military designs. The /883B designation indicates it meets specific military screening and quality assurance requirements distinct from commercial variants.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other PAL20R8 variants from different manufacturers such as Texas Instruments or Lattice, provided they support the same registered output configuration and TTL voltage levels. Verify timing parameters match the 45ns requirement.
