Description and Introduction

Progammable Array Logic Series 24 (PAL Series 24) The **PAL16R8JC** from National Semiconductor (NS) is a programmable array logic (PAL) device designed for high-speed digital logic applications. As part of the PAL16R8 series, it features a fixed OR-array architecture with programmable AND gates, allowing for flexible logic implementation while maintaining performance.  

This 20-pin DIP (Dual In-Line Package) component operates with a registered output structure, making it suitable for sequential logic designs such as state machines, counters, and control systems. The **PAL16R8JC** supports eight registered outputs with individual output enable controls, enhancing design versatility.  

Key specifications include a typical propagation delay of **25 ns**, ensuring reliable performance in medium-speed applications. The device is compatible with industry-standard PAL programming tools, simplifying development and integration into existing systems. Its robust design and wide operating voltage range (typically **4.5V to 5.5V**) make it a dependable choice for industrial and embedded applications.  

While newer CPLDs and FPGAs have largely replaced PAL devices in modern designs, the **PAL16R8JC** remains relevant for legacy system maintenance and cost-sensitive projects requiring deterministic logic. Its straightforward architecture and proven reliability continue to support engineers in specialized applications.

Application Scenarios & Design Considerations

Progammable Array Logic Series 24 (PAL Series 24)

Alternative Part Number

  • GAL16V8D-15LJ --: Generic array logic device that is a functional replacement for the PAL16R8, offering the same 16-input 8-output architecture and commonly used as a direct upgrade.
  • ATF16V8B-15JC --: High-performance CMOS PLD electrically compatible with 16R8-type PALs, suitable for replacing the PAL16R8JC in existing sockets.
  • TIBPAL16R8-15CN --: Pin-compatible PAL16R8 device from a different series, providing equivalent 16-input 8-register-output logic functionality.
