TIBPAL16L8-15CFN

Overview

The TIBPAL16L8-15CFN is a High-Performance IMPACT PAL circuit featuring 10 dedicated inputs, 6 I/O ports, and 2 outputs. It utilizes Advanced Low-Power Schottky technology with titanium-tungsten fuses for reliable performance. The device operates within a 4.75 V to 5.25 V supply range. Maximum propagation delay is 15 ns from input to output and 12 ns from clock to registered output. It supports a maximum clock frequency of 50 MHz.

Feature Summary

• Functionally equivalent but faster than standard PAL16L8A devices
• Combines high-speed operation with low power consumption
• Provides flexible design options through easy programmability

Applications

• Digital signal processing bus interfaces
• Video encoder and decoder boards
• ISDN peripheral interface circuits
• Custom logic function implementation on compact circuit boards

Procurement Notes

This specific part number is listed as obsolete in official documentation. Verify current availability status and lifecycle stage before procurement planning. Consider alternative package suffixes or updated series members if long-term supply continuity is required for new designs.

Selection Notes

Select this device when replacing legacy PAL16L8A circuits requiring higher speed. Ensure the application fits the 0°C to 75°C commercial temperature range. Verify that the 20-pin PLCC package matches the target board layout constraints.

Part Context

Part of the Texas Instruments IMPACT PAL family designed to replace conventional TTL logic. These circuits offer simplified custom function design and reduced board space compared to discrete logic solutions. The family includes various speed grades and package options for different environmental requirements.

Replacement Considerations

Verify pinout compatibility with existing PAL16L8A implementations. Confirm that the 15 ns speed grade meets system timing requirements. Check for available active alternatives in the same package style if the obsolete status impacts production.
