AFAIK there isn’t a library of 74 series parts but there are a fair number of examples around. Here is a set that I have from various places (some I have made, some I have collected from the forum or the net.) 74x125.fzpz 74x126.fzpz 74x367.fzpz 74AHCT125.fzpz 74HC00.fzpz 74HC47.fzpz 74HC165.fzpz 74HC4051.fzpz 74HCT245.fzpz 74LS04.fzpz 74LS08.fzpz 74LS32.fzpz 74LS74.fzpz 74LS86.fzpz 74LS393N.fzpz A google search of the form “fritzing part 74ls86” will turn up anything that is available. You look to be using generic ICs, you can add labels to the pins by clicking Edit pin labels in Inspector (the lower right window.) ![capture](https://forum.fritzing.org/uploads/default/original/2X/e/eff6c86fa4f982392ce9a7af783faf9a918d506a.jpeg) If you are willing to do a fair amount more work (and someone in the forum was doing such work as part of a project to create schematics from existing pc boards and has uploaded at least some of his parts) you can make custom parts where the individual sections can move independently in schematic like this (which is the 74x125.fzpz file in my list) default load: ![capture1](https://forum.fritzing.org/uploads/default/original/2X/5/527ac06221e14b0df201e4fc74445b441fec8e12.jpeg) click on an element and move it around ![capture2](https://forum.fritzing.org/uploads/default/original/2X/6/6031e1aeb97c99e357347811cf3fdf0d75f8df50.jpeg) with the internal logic being represented. Instructions on how to do that are available in this tutorial set on part making (but part making in general is fairly complex, and variable subparts are one of the more complex features!) > [@Part creation howto part 1 breadboard and pcb](https://forum.fritzing.org/t/part-creation-howto-part-1-breadboard-and-pcb/7692): > > Someone in this forum post requested help to fix up a part. So while doing that I decided to record what I needed to do in order to fix the part to provide a tutorial to create new / fix broken parts. If you start from the Tarjeta S4A EDU.fzpz file posted in the above thread, you should be able to recreate my improved part posted in the same thread. I started by loading the original part in to Fritzing, that indicates breadboard is (at first look anyway) pretty good, but schematic and pcb are… there are 10 or 11 parts to this series and I think one of them covers schematic subparts.
