Hi Ken. Don't mean to insult, you are one of my favourite YouTubers alongside Marc. But your logic diagram has a slight error. Your P and G outputs are back to front compared to the original diagram from the datasheet. The G out should be from the 4-input NOR gate and the P from the 4-input NAND gate.
