Here is a list of ICs(Integrated Circuits of the series 74xx) with their Number and Functions. The links will take you to their Pin Out Diagrams. As a Physics student I always felt the need of a quick reference hand/pocket-book while carrying out the practicals in my electronics lab. So I took some time out to build an App(only for windows OS/phones) that would provide the details of each IC quickly and beautifully. If you like the idea here is the link to the app:Microsoft Store Page

I’m a physicist specializing in computational material science with a PhD in Physics from Friedrich-Schiller University Jena, Germany. I write efficient codes for simulating light-matter interactions at atomic scales. I like to develop Physics, DFT, and Machine Learning related apps and software from time to time. Can code in most of the popular languages. I like to share my knowledge in Physics and applications using this Blog and a YouTube channel.
