Procurement Notes

Verify the specific suffix 'ACFN' against official Texas Instruments documentation to confirm temperature range and package variant. Ensure compatibility with existing design files and programming tools. Confirm that the component meets all required environmental standards for the intended application environment before procurement.

Selection Notes

Select this device when a simple PLD with TTL compatibility is required for moderate complexity logic designs. Consider the Impact-XE series for improved performance over legacy PAL devices. Evaluate pin count and I/O requirements to ensure the 22-input/10-output configuration matches the system needs without excessive resource usage.

Part Context

This component belongs to the Texas Instruments Impact-XE family of programmable logic devices. These circuits are designed as drop-in replacements for older PAL architectures while offering better performance characteristics. The family includes various speed grades and package options to suit different design constraints.

Replacement Considerations

Direct substitutes include other TIBPAL22V10 variants with different speed grades or package types, such as TIBPAL22V10-20MFN. Verify electrical parameters and pinout compatibility before substitution. Legacy PAL devices may require firmware reprogramming if logical functionality differs.
