PAL

PAL, or Programmable Array Logic, is a type of digital device used to implement custom logical functions. Think of it as a flexible electronic "rulebook" that can be programmed to perform specific logic operations, such as AND, OR, and NOT, based on user-defined settings. Engineers use PALs to create custom digital circuits efficiently, replacing complex wiring or multiple smaller components with a single, programmable chip. This versatility makes PALs useful in applications like controlling signals, processing data, or managing automation tasks in various electronic systems.
