TIBPAL16L8-15CN

Overview

The TIBPAL16L8-15CN is a high-performance IMPACT PAL circuit featuring 10 dedicated inputs, 6 I/O lines, and 2 registered outputs. It operates with a maximum propagation delay of 15 ns from input to output and 12 ns from clock to register output. The device supports a maximum clock frequency of 50 MHz and functions within a supply voltage range of 4.75 V to 5.25 V. It is characterized for operation over an operating free-air temperature range of 0°C to 75°C.

Feature Summary

• Combines Advanced Low-Power Schottky technology with titanium-tungsten fuses for reliable high-speed performance.
• Provides power-up clear functionality where all register outputs initialize to a high state upon power application.
• Offers functional equivalency to older PAL16L8A devices while delivering faster switching speeds.

Applications

• State machine implementation requiring rapid initialization.
• High-speed decoding logic in industrial control systems.
• Replacement for legacy TTL logic in military-grade environments.
• Custom function design for compact circuit board layouts.

Procurement Notes

Verify the specific package suffix 'N' corresponds to the Plastic DIP (PDIP) configuration as indicated in the Package Option Addendum. Confirm that the 'C' suffix aligns with the commercial temperature range requirements of 0°C to 75°C. Ensure programming equipment supports the titanium-tungsten fuse architecture specified for this IMPACT series device.

Selection Notes

Select this component when a direct replacement for PAL16L8A is needed with improved speed characteristics. Choose the 'C' suffix variant for applications operating between 0°C and 75°C. Consider the registered output configuration if state storage is required, noting that the L8 variant provides two registered outputs alongside combinational I/O ports.

Part Context

This device belongs to the Texas Instruments IMPACT PAL family, which utilizes Advanced Low-Power Schottky technology. It serves as a high-performance substitute for conventional TTL logic, allowing for custom function design and reduced board space through programmable array logic architecture.

Replacement Considerations

The TIBPAL16L8-15CN is functionally equivalent but faster than the PAL16L8A. For military temperature ranges (-55°C to 125°C), consider the M suffix variants such as TIBPAL16L8-20M. Verify pinout compatibility when substituting into existing designs utilizing older PAL architectures.
