741/555/431

you can find uA741 and 555 in every basic circuit book, these are study examples for analog designer

www.designinganalogchips.com is the home page of the designer's of the 555 (Hans Camenzid)

But it is not clear for me, maybe you are looking for application. This topic is for IC design, not for application design.
