TIBPAL16R6-5CFN

Overview

The TIBPAL16R6-5CFN is a high-performance IMPACT-X PAL circuit manufactured by Texas Instruments. It features Advanced Low-Power Schottky technology with titanium-tungsten fuses, providing reliable operation as a substitute for conventional TTL logic. The device operates within a commercial temperature range of 0°C to 75°C and supports a supply voltage of 4.75V to 5.25V. Key electrical characteristics include a maximum propagation delay of 5ns from input to output and a clock-to-Q delay of up to 4.5ns. It achieves a minimum frequency without feedback of 125MHz.

Feature Summary

• High-speed performance with 125MHz minimum frequency (no feedback) and 5ns max propagation delay
• Registered outputs with asynchronous preload capability for simplified testing
• Power-up clear feature resets all registers to zero upon initialization
• Security fuse prevents unauthorized duplication of the programmed logic

Applications

• High-speed state machine designs requiring external feedback
• Counter configurations utilizing internal feedback paths
• Custom logic functions replacing conventional TTL gates
• Systems requiring registered outputs with specific power-up states

Procurement Notes

Verify the package type matches the 'FN' suffix designation, which corresponds to a plastic chip carrier format. Confirm the '5C' suffix indicates the commercial temperature grade (0°C to 75°C). Ensure programming equipment supports the IMPACT-X architecture and titanium-tungsten fuse technology specified in the datasheet.

Selection Notes

Select this component when registered outputs are required alongside high-speed combinatorial logic. The TIBPAL16R6 variant provides 8 dedicated inputs, 2 I/O lines, and 6 registered Q outputs. Compare against the TIBPAL16R8 if more registered outputs are needed or the TIBPAL16L8 if registered outputs are unnecessary. Consider thermal management requirements for simultaneous switching outputs at high frequencies.

Part Context

This part belongs to the TIBPAL16 series of IMPACT-X PAL circuits, which includes variants like TIBPAL16R4, TIBPAL16R6, and TIBPAL16R8. The series is designed to be functionally equivalent but faster than existing 20-pin PLDs. The '5C' designation distinguishes it from the '7M' military-grade series, offering higher speed specifications within the commercial temperature range.

Replacement Considerations
