Wonderful stuff. I am old enough to remember its introduction and have used it many times in my designs over the years. Also fallen into the "crowbar" trap presented with the bipolar versions, especially when working within circuits containing counters or processors etc. where without adequate precautions the 555 will present a microscopic short on the supply rails at switch over and create havoc. Also found it useful as an auto reset device for remote processor based systems (by remote I mean physically remote as in some weather stations) If you gate the address / data lines into a 555 configured as a "missing pulse detector" then should the system freeze, the output of the 555 can be used to perform a reset hopefully restoring function to the system.
