555 Timer resources

History

There are few inaccurate histories of the 555 timer invention on the web so a good source is from the designer himself, e.g., http://semiconductormuseum.com/Transistors/LectureHall/Camenzind/Camenzi... [1]

He also wrote several interesting books. The history and detailed design considerations are covered in a book he kindly made available as a PDF file before his death in 2012: http://www.designinganalogchips.com/_count/designinganalogchips.pdf [2]

Circuits

This is a reasonable compendium of interesting circuits using the IC: http://www.555-timer-circuits.com [3]

Variations

The CMOS versions of the 555 timer are interesting and lend themselves well to low voltage e-textile applications. My favorite variant is this one: https://www.jameco.com/z/CSS555-ID-Custom-Silicon-Solutions-CSS555-Micro... [11]

Here is the largest variant I know of: https://shop.evilmadscientist.com/productsmenu/tinykitlist/652-555kit [12]

and the smallest (a 1mm x 1mm) package:
