Description and Introduction

Progammable Array Logic Series 24 (PAL Series 24) **Introduction to the PAL18L4NC from National Semiconductor**  

The PAL18L4NC is a programmable array logic (PAL) device developed by National Semiconductor (NS). As part of the PAL family, it is designed for digital logic applications requiring high-speed performance and flexible programmability. The device features a fixed OR array and a programmable AND array, allowing users to implement custom logic functions efficiently.  

With 18 inputs and 4 outputs, the PAL18L4NC is well-suited for applications such as address decoding, state machine control, and interface logic. It operates at low power while maintaining fast propagation delays, making it a reliable choice for embedded systems and industrial electronics. The device is fabricated using CMOS technology, ensuring low power consumption and compatibility with modern logic designs.  

The PAL18L4NC is programmed using industry-standard tools, enabling engineers to define logic equations tailored to specific requirements. Its one-time programmable (OTP) architecture ensures stable performance in long-term applications.  

As a versatile and cost-effective solution, the PAL18L4NC remains a practical option for designers seeking a balance between performance and simplicity in programmable logic. Its integration capabilities and robust design make it a valuable component in various digital systems.

Application Scenarios & Design Considerations

Progammable Array Logic Series 24 (PAL Series 24)

Alternative Part Number

  • GAL18LV8Z --: Generic Array Logic device in the same 18-input class with low-voltage operation, a common drop-in replacement for PAL18L4 designs.
  • ATF16V8C --: Popular low-power SPLD with 16V8 architecture that can emulate many 18L4 PAL functions and is widely available.
  • PALCE16V8H --: CMOS PAL device with similar logic capacity and low power consumption, suitable as a functional substitute for legacy PAL18L4 parts.
