pike Member Feb 19, 2004 #2 I think the '3909 is out dated by other devices such as the '555. Why would you need a '3909??
A alanzhao New Member Feb 20, 2004 #3 well, I thought it's simpler to use than 555 timer and wonder if people are still using it for their project. Is it a good idea to collect obselete parts?

lavenatti Member Feb 20, 2004 #4 The lm3909 will flash an LED for several years on a D battery. A 555 won't last more than a month or two . It never hurts to have some outdated stuff, it's not like they take up much room and sometimes you need these parts for repairs.
