TIBPAL16R4-15CN

Overview

The TIBPAL16R4-15CN is a high-performance IMPACT PAL programmable logic device featuring Advanced Low-Power Schottky technology. It provides a maximum propagation delay of 15 ns and operates with a nominal supply voltage of 5 V. The device includes four registered outputs with three-state buffers, eight inputs, and six I/O ports. It is characterized for operation within an ambient temperature range of 0°C to 75°C.

Feature Summary

• High-speed logic implementation using titanium-tungsten fuses
• Registered outputs feature power-up clear initialization
• Functionally equivalent to legacy PAL16R4A devices

Applications

• State machine control logic
• Address decoding circuits
• Bus interface arbitration
• Custom combinational logic replacement

Procurement Notes

Verify the specific package marking and manufacturer date code upon receipt. Confirm that the component matches the exact suffix requirements for your thermal environment. Check for any obsolescence notices or lifetime buy announcements from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this device when a fast PAL architecture with registered outputs is required. Ensure the design utilizes the 5 V supply rail strictly. Verify that the pinout compatibility meets the existing board layout constraints compared to standard PAL16R4A equivalents.

Part Context

This component belongs to the TIBPAL16 family of IMPACT PAL circuits. It serves as a direct functional upgrade to older PAL16R4A parts, offering improved speed and reliability through advanced semiconductor manufacturing processes while maintaining identical logical functionality.

Replacement Considerations

The TIBPAL16R4A is the primary legacy counterpart. When replacing obsolete units, verify that the new device supports the same fuse map and electrical characteristics to ensure seamless integration without redesigning the surrounding circuitry.
