Comments on 22V10 PLD
The 22V10 PLD is a example of a more complex PAL. We will use this device in Lab.
The ‘macrocell’ has a memory device called a Flip-Flop inside of it - we will discuss this later in the course.
- In our initial use of the 22V10 PLD, the macrocell will just pass the OR gate output unchanged to the output pin.
The output of the Macrocell is passed back into the array as an input - this way complex functions be created by ‘chaining’ functions together.
