Not wanting to hijack a thread, http://forum.allaboutcircuits.com/threads/time-delayed-switch-trigger-by-opening.113144/ it was perfect for a question I have. Why doesn't anyone use any of the other timers, other than a 555? It seems to be the only one people use.
The cd4538, cd4098, and many others seem to do things that the 555 can't. The main one being able to use either a rising or falling edge as a trigger. They can be used as an astable or monostable and have many of the same traits as the 555.
Another of my 'million dumb questions'.
