Question

Quizplus · Accepted Answer

PAL (Programmable Array Logic) devices have a programmable AND array that allows for the customization of the logic device to the user's needs, while the OR array is fixed (hard-wired), making the choice of inputs to the OR gates predetermined. This structure allows for flexibility in creating logic functions while maintaining a simpler, more cost-effective design compared to fully programmable logic devices.
