TIBPAL16L8-10CFN

Overview

The TIBPAL16L8-10CFN is a high-performance IMPACT-X PAL circuit featuring 16 inputs and 8 combinatorial outputs. It operates within a commercial temperature range of 0°C to 75°C with a maximum propagation delay of 10 ns. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliable performance.

Feature Summary

• Combines high-speed operation with functional equivalency to conventional TTL logic
• Includes security fuse functionality to prevent unauthorized duplication
• Offers flexible package options including plastic and ceramic chip carriers

Applications

• Replacement for existing 20-pin programmable logic devices requiring faster performance
• Custom function design in compact circuit boards
• Digital signal processing bus interface circuits
• Video encoder and decoder peripheral interfaces

Procurement Notes

Verify the specific suffix 'CFN' corresponds to the Plastic Chip Carrier package variant. Confirm that the 'C' suffix indicates the commercial temperature grade (0°C to 75°C) rather than the military grade. Ensure programming equipment supports the titanium-tungsten fuse architecture specified for this IMPACT-X series.

Selection Notes

Select this component when a direct replacement for legacy PALs is needed with improved speed characteristics. The combinatorial output configuration suits applications not requiring registered storage. Consider the CFN package dimensions for board space constraints compared to DIP alternatives.

Part Context

This device belongs to the Texas Instruments IMPACT-X PAL family, designed as high-performance substitutes for standard logic. The TIBPAL16L8 variant specifically provides combinatorial logic without registered outputs, distinguishing it from the R4, R6, and R8 registered counterparts within the same datasheet.

Replacement Considerations

Publicly confirmed substitutes include other TIBPAL16L8 variants with different speed grades or package suffixes, such as TIBPAL16L8-12MFKB. Verify pin compatibility and electrical specifications before substituting across different speed or temperature grades.
