TIBPAL16R8-12MFKB

Overview

The TIBPAL16R8-12MFKB is a High-Performance IMPACT-X PAL circuit manufactured by Texas Instruments. It features an 8-bit registered output architecture with 8 inputs and 8 I/O ports in a 20-pin package. The device utilizes Advanced Low-Power Schottky technology for high-speed operation, achieving a minimum fmax of 56 MHz without feedback and 48 MHz with feedback. Propagation delay from input to output is 12 ns maximum, while clock-to-Q delay is 10 ns maximum. It operates over the full military temperature range of -55°C to 125°C.

Feature Summary

• High-performance IMPACT-X architecture using titanium-tungsten fuses
• Registered outputs with preload capability for simplified testing
• Power-up clear feature sets all registers to low level initially
• Security fuse prevents logic duplication

Applications

• High-speed state machine implementations
• Register file designs requiring fast clock frequencies
• Military-grade logic replacement applications

Procurement Notes

Verify the M suffix indicates the -55°C to 125°C military temperature range and FK suffix denotes the ceramic chip carrier package. Confirm the specific revision status as the datasheet notes this series may be obsolete or not recommended for new designs depending on the exact sub-model variant.

Selection Notes

Select this component when military temperature tolerance (-55°C to 125°C) is required alongside registered outputs. Ensure the design accommodates the 12 ns max propagation delay and 56 MHz max frequency. Verify that the 20-pin ceramic package fits the board layout constraints compared to plastic alternatives.

Part Context

This part belongs to the TIBPAL16R8 family of programmable array logic devices. It is functionally equivalent to standard PAL16R8 circuits but offers faster performance through IMPACT-X technology. The '12' designation specifies the 12 ns speed grade within the military temperature range series.

Replacement Considerations

Standard PAL16R8 devices are functionally similar but lack the IMPACT-X speed and military rating. Check for direct pin-compatible replacements in the TIBPAL16L8 or TIBPAL16R6 families if fewer registered outputs are acceptable.
