TIBPAL16R6-7CFN

Overview

The TIBPAL16R6-7CFN is a High-Performance IMPACT-X PAL circuit manufactured by Texas Instruments. It features an 8-input, 6 registered output (Q), and 2 I/O port architecture within a 20-pin Plastic Flatpack (FN) package. The device operates at a maximum clock frequency of 100 MHz with a typical propagation delay of 5 ns from CLK to Q. It utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliable high-speed performance. The component supports preload capability on output registers and includes a security fuse to prevent duplication.

Feature Summary

• High-performance operation with a minimum fmax of 100 MHz in no-feedback and internal feedback configurations.
• Registered output architecture providing 6 dedicated Q outputs and 2 I/O ports.
• Preload capability allows asynchronous loading of registers to simplify testing sequences.
• Power-up clear feature resets all registers to a low level upon initialization.

Applications

• Counter designs utilizing internal feedback paths.
• On-chip state-machine implementations requiring registered outputs.
• Custom logic functions replacing conventional TTL logic gates.
• Systems requiring secure programmable logic with anti-duplication features.

Procurement Notes

Verify the specific suffix 'CFN' corresponds to the Plastic Flatpack package variant. Confirm that the 'C' suffix indicates the commercial temperature range of 0°C to 75°C. Check current availability status as this series may be obsolete or limited in production supply.

Selection Notes

Select the TIBPAL16R6-7CFN when six registered outputs are required alongside two bidirectional I/O lines. Choose the '-7C' speed grade for applications demanding up to 100 MHz clock frequencies. Ensure the design accommodates the 20-pin FN package dimensions if board space reduction is a priority over DIP packages.

Part Context

This component belongs to the TIBPAL16 family of IMPACT-X PAL circuits. It shares functional similarities with the TIBPAL16L8, TIBPAL16R4, and TIBPAL16R8 variants, differing primarily in the number of registered outputs and I/O ports available on the 20-pin footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Equivalent functionality may be found within the broader TIBPAL16 series or modern SPLD replacements, but direct pin-for-pin substitution requires verification against specific application constraints.
