Timer off

Does anyone know of a circut that will set its output high for xx time and then output goes low even if trigger stays high?

4038/4538 is a dual timer; it is edge triggered, so it should work for you (make certain the other trigger is tied toits idle rail...). HOWEVER---you can tie pin 2 of 555 high with a 100k, and trigger through a .01µF cap--should work fine...<p>(a 555 of course triggers on LOW...)
