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.
As I promised, here is a outline of the steps I go through to make the weekly IC Friday posts. First, a word of caution:
Handling sulfuric acid REQUIRES specialized training and equipment. Misuse can result in serious injury or death. Furthermore, improper disposal can cause serious illness to others and permanent damage to your workspace. Finally, adequate ventilation/fume extraction is a MUST when heating sulfuric acid.
Today’s IC Friday entry is the 8bit AVR micro from Atmega. This chip was sent in by a reader, all the way from Iceland.
Today’s entry is the LMC6042 dual-op amp from National Semiconductor. The layout of this device is a bit different from a standard op-amp due to the inclusion of some periodic components. It can also be noted that this die is mostly the same as the LMC6044 except that the two op-amps on the bottom-right side of the chip don’t have most of the metal deposited.
