AMPAL22P10ALJC

Overview

The AMPAL22P10ALJC is a programmable logic device (PLD) manufactured by Advanced Micro Devices, formerly Xilinx. It belongs to the PAL-type family and operates with a propagation delay of 25 nanoseconds. The component supports TTL logic levels and is housed in a 28-pin PLCC package measuring 11.51x11.51 mm. This integrated circuit is categorized under embedded logic solutions.

Feature Summary

• PAL-type architecture for fixed-function logic implementation
• TTL-compatible input and output logic levels
• 25 nanosecond propagation delay specification

Applications

• General-purpose digital logic replacement
• TTL interface adaptation
• Embedded control logic circuits

Procurement Notes

Verify the manufacturer origin, noting that Xilinx was acquired by AMD. Confirm the specific package dimensions match the 28-PLCC standard. Ensure the device meets the required 25ns timing constraints for your application. Check for any obsolescence notices from the current manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a simple PAL-type solution is sufficient for logic functions. The 25ns speed is suitable for moderate-frequency applications. Consider the 28-pin PLCC footprint for PCB layout compatibility. Verify TTL voltage requirements against system power rails.

Part Context

This part is part of the legacy Xilinx PAL series, now managed by AMD. It represents a standard fixed-function programmable logic device used for replacing discrete logic gates. The product line focuses on cost-effective logic integration for established digital designs.

Replacement Considerations

Check for direct pin-to-pin replacements within the same PAL family. Verify if newer CPLD alternatives offer better density or speed while maintaining compatible interfaces.
