TIBPAL16R6-25CFN

Overview

The TIBPAL16R6-25CFN is a low-power, high-performance IMPACT PAL programmable logic device manufactured by Texas Instruments. It features registered outputs and operates with a maximum propagation delay of 25 ns. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliable performance. It is characterized for operation over the commercial temperature range of 0°C to 75°C. The unit is housed in a 20-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Registered output architecture with power-up clear functionality
• Maximum propagation delay of 25 ns from input/output to output
• Compatible with standard 5 V supply voltage (4.75 V to 5.25 V)
• Commercial temperature rating from 0°C to 75°C

Applications

• State machine implementation requiring registered outputs
• High-speed digital logic replacement for conventional TTL circuits
• Custom function design in compact circuit boards

Procurement Notes

This component is classified as LIFEBUY status by Texas Instruments. This indicates that production has been discontinued, but a lifetime-buy period is currently in effect. Verify current availability windows through authorized distributors or TI field sales offices before finalizing procurement plans.

Selection Notes

Select this part when registered outputs are required for state-holding applications. The '25' suffix specifies a 25 ns speed grade, while 'CFN' denotes the PLCC package. Ensure the design supports the 0°C to 75°C operating range; for military temperatures (-55°C to 125°C), consider the M-suffix variants.

Part Context

The TIBPAL16R6-25CFN belongs to the TIBPAL16 family of IMPACT PAL circuits. It is functionally equivalent to but faster than legacy PAL16R6A devices. The R6 designation indicates six registered outputs, eight dedicated inputs, and two I/O ports within the 20-pin configuration.

Replacement Considerations

Publicly confirmed substitute part numbers include TIBPAL16R6-30MFKB and TIBPAL16R6-30MJ. These alternatives offer different speed grades or packages but maintain functional compatibility within the same device family.
