PAL20L8AMW/883B

Programmable Logic Device Pld Overview

The PAL20L8AMW/883B is a high-performance 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 CDFP20 package, specifically a 0.250 x 0.500 inch Cerpack-20 ceramic flatpack. It operates within an extended temperature range of -55°C to +125°C. The device provides 20 dedicated inputs and 8 outputs with combinatorial output functions, housed in a metal-sealed co-fired ceramic body suitable for military or aerospace environments.

Programmable Logic Device Pld Feature Summary

• PAL-type architecture with 45ns propagation delay
• 20-pin Ceramic Flatpack (CDFP20) package
• -55°C to +125°C operating temperature range
• TTL-compatible inputs with combinatorial outputs

Programmable Logic Device Pld Applications

• Military avionics logic control
• Aerospace signal processing
• High-reliability industrial automation systems

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the /883B suffix, which indicates screening to MIL-STD-883 standards. Confirm the specific AMD manufacturer lot date code due to the component's age. Ensure the ceramic flatpack pins are free from oxidation before soldering. Request detailed test data for leakage current and switching times if used in critical safety applications.

Programmable Logic Device Pld Selection Notes

Select this part when a 20-input, 8-output PAL solution is required for harsh environments. The /883B variant is necessary for radiation hardness and thermal stability requirements exceeding commercial grades. Compare against PAL16L8 variants if fewer inputs are sufficient, noting the pinout differences between DIP and flatpack packages.

Programmable Logic Device Pld Part Context

This component belongs to the AMD PAL16/20 family of programmable logic devices. The /883B designation signifies compliance with Department of Defense screening standards. It serves as a legacy replacement for discrete gate arrays in established military hardware designs requiring deterministic timing and high noise immunity.

Programmable Logic Device Pld Replacement Considerations

Direct pin-for-pin replacements include other AMD PAL20L8 variants with the same package. Cross-manufacturer equivalents such as Lattice GAL20V8 may require logic reprogramming and voltage level verification. Ensure the substitute supports the required 45ns speed and 125°C maximum temperature.
