Programmable Array Logic (PAL) is a type of digital device used in electronic circuits to implement combinational logic functions. It consists of a fixed OR array and a programmable AND array, allowing designers to customize the logic functions according to their needs. This flexibility makes PALs suitable for various applications, including simple logic operations and more complex digital systems. PALs are often used in field-programmable gate arrays (FPGAs) and other programmable logic devices. They provide a cost-effective solution for creating specific logic functions without the need for custom hardware. Their ease of use and reprogrammability make them popular in both prototyping and production environments.
