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

If you find the post useful but use an Android or Apple based system, here is a link to the PDF version>>
