PAL16L8-7JC

Programmable Logic Device Pld Overview

The PAL16L8-7JC is a high-speed Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It features an architecture with 16 input lines and 8 output lines, providing 64 product terms for complex logic implementation. The component operates with a maximum propagation delay of 7 nanoseconds, ensuring rapid signal processing in digital circuits. It utilizes a 20-pin Plastic Quad Flatpack (PQCC) package, specifically designated as LCC-20, which facilitates surface-mount assembly. The device functions within standard TTL voltage levels and is designed for combinatorial logic applications requiring fast switching speeds and reliable performance in industrial or commercial environments.

Programmable Logic Device Pld Feature Summary

• Features a dedicated PAL-type architecture optimized for high-speed combinatorial logic operations
• Provides extensive programmability through 64 product terms to implement complex Boolean functions
• Incorporates active low output capability for direct interfacing with various digital logic families

Programmable Logic Device Pld Applications

• High-speed address decoding in memory systems
• Bus protocol translation between different logic families
• State machine implementation in control circuits
• General-purpose combinatorial logic replacement

Programmable Logic Device Pld Procurement Notes

Verify the specific manufacturer source, as Vantis assets were acquired by AMD and later Lattice Semiconductor. Confirm that the component matches the original Vantis specifications rather than subsequent rebrands. Ensure the package type corresponds to the 20-pin plastic quad flatpack variant. Check for RoHS compliance status if required for modern manufacturing standards, noting that older versions may not meet current environmental regulations.

Programmable Logic Device Pld Selection Notes

Select this component when a fixed-function PAL solution is preferred over flexible CPLDs for cost-sensitive, high-volume designs. The 7ns speed grade is suitable for systems requiring moderate clock frequencies without the complexity of programmable interconnects. Consider the 16x8 I/O configuration against system requirements to ensure sufficient pins are available. Evaluate the PQCC package availability against PCB layout constraints and automated assembly capabilities.

Programmable Logic Device Pld Part Context

This device belongs to the classic GAL/PAL family of programmable logic devices, widely used before the dominance of FPGAs. Vantis Corporation was a significant player in this market before its acquisition. These components remain relevant for legacy system maintenance and simple logic replacement where programming tools are already established. The PAL16L8 variant is a standard part number in the industry, often cross-referenced with similar parts from other manufacturers like AMD or Lattice.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes include PAL16L8 variants from AMD or Lattice Semiconductor with identical pinouts and logic functionality. Verify that replacement parts maintain the 7ns speed grade and 20-pin PQCC package. Ensure that any alternative maintains the same electrical characteristics and output drive capabilities.
