PAL20X8AML883B

Programmable Logic Device Pld Overview

The PAL20X8AML883B is a high-performance Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices (AMD). It features an OT PLD architecture with a propagation delay of 45ns and TTL compatibility. The component utilizes a CDFP-20 ceramic flatpack package, measuring 0.250 x 0.500 inches. It operates within an extended temperature range from -55°C to +125°C. The device provides 20 dedicated inputs and 8 registered outputs, configured for complex combinatorial and registered logic functions in military-grade applications.

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'AML883B' against official AMD documentation to confirm pinout and electrical characteristics match the standard PAL20X8 family. Ensure the supplier provides traceability certificates required for MIL-STD components. Confirm RoHS exemption status as indicated by the 883B designation.

Programmable Logic Device Pld Selection Notes

Select this part when a registered output configuration with 20 inputs is required for harsh environment applications. Compare the 45ns speed against faster GAL or CPLD alternatives if timing constraints are critical. Verify that the CDFP-20 footprint matches the PCB design, as lead form variations exist within the same logical family.

Programmable Logic Device Pld Part Context

This component belongs to the AMD PAL20X8 family of programmable logic devices. The '883B' suffix indicates compliance with MIL-PRF-38534 Class B specifications, denoting full screening and testing for military and space applications. It serves as a drop-in replacement for earlier PAL20X8 variants in legacy military hardware designs.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other PAL20X8 variants with matching speed grades and package types. Verify that any substitute maintains the registered output structure and TTL voltage levels. Cross-reference with AMD's obsolescence notices to ensure long-term availability for sustained production runs.
