Used these to provide isolation for sensitive audio announcement device. A long pulse from a relay needed to be shortened. Two resistors and a large capacitor did the trick. Simple and inexpensive.

I love these things! It was either this or a relay... opto rocks for electrical isolation and even opamps that wont go rail to rail, this iten fixes that!
