TIBPAL16R6-15CFN

Overview

The TIBPAL16R6-15CFN is a High-Performance Impact PAL circuit from Texas Instruments, characterized for operation between 0°C and 75°C. It features an Advanced Low-Power Schottky architecture with titanium-tungsten fuses. The device provides 8 dedicated inputs, 2 dedicated outputs, and 6 registered I/O ports capable of 3-state buffering. Maximum propagation delay is 15 ns from input to output and 12 ns from clock to registered output. It operates at a maximum clock frequency of 50 MHz with a nominal supply voltage of 5 V.

Feature Summary

• High-performance logic using Advanced Low-Power Schottky technology
• Registered outputs with power-up clear feature
• Functional equivalence to PAL16R6A with improved speed
• Titanium-tungsten fuse programming for reliability

Applications

• State machine implementation
• Register file design
• Bus interface logic

Procurement Notes

Verify the obsolete status of this component before procurement. Confirm that existing inventory or lifetime buy options are available if required for maintenance. Ensure programming equipment supports titanium-tungsten fuse technologies. Validate that the 0°C to 75°C temperature range meets system requirements.

Selection Notes

Select this part when registered outputs with 3-state capability are needed in a compact PLD format. Compare against the 20M suffix variant if military temperature ranges (-55°C to 125°C) are required instead of commercial ranges. Consider board space reduction benefits over discrete TTL logic solutions.

Part Context

This device belongs to the TIBPAL16 family of programmable array logic circuits. It serves as a high-speed replacement for older PAL16R6A devices. The 'C' suffix denotes the commercial temperature grade, while 'FN' indicates the PLCC package option.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Legacy equivalents include the PAL16R6A.
