TIBPAL20L8-15CNL

Overview

The TIBPAL20L8-15CNL is a high-performance programmable logic device (PLD) from Texas Instruments, belonging to the Impact PAL circuit family. It features a 15ns propagation delay and operates on a 5V supply voltage. The component utilizes a 28-pin PLCC package for surface-mount integration. Designed for complex logic implementation, it supports up to six inputs and outputs within its architecture. This device provides reliable digital switching capabilities suitable for embedded processor applications and general-purpose logic control tasks requiring fast response times.

Feature Summary

• High-speed logic processing with 15ns propagation delay
• Integrated programmable array logic architecture
• Surface-mount compatible 28-pin PLCC packaging

Applications

• Embedded processor interface circuits
• General-purpose digital logic control
• Address decoding systems

Procurement Notes

Verify the specific suffix CNL confirms the 28-pin PLCC package variant when sourcing. Ensure compatibility with standard 5V logic levels required by the Impact PAL series. Cross-reference datasheets to confirm pinout alignment for PCB layout. Validate that the component meets the intended operating temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this model when a 15ns speed grade is required for logic functions. The 28-pin PLCC form factor suits surface-mount designs needing compact footprints. Consider the six I/O limit for complexity requirements. Compare against other Impact PAL variants if different package types or speed grades better fit the board space constraints.

Part Context

This component belongs to the Texas Instruments Impact PAL series, designed for high-density logic replacement. It serves as a direct upgrade for older discrete gate solutions. The series offers flexibility in implementing combinational and registered logic functions. It is widely used in industrial and consumer electronics for signal routing and control.

Replacement Considerations

Direct substitutes include the TIBPAL20L8-15CNT for DIP packaging or the TIBPAL20L8-20M for alternative speed/package combinations. Verify logical equivalence and pin compatibility before swapping.
