“I have many AS and LS series logic gates lying around, so I figured that I would image some as they would be more instructive than looking at the latest CPUs coming out of Intel. I have a few more lined up so please comment if you want me to follow this reasoning. Today’s subject is a hex-inverter, the 74AS04. Below are images of the whole chip and a blowup of the top-right inverter gate.”
