I found a 556 in my junque box, and thought it'd be fun to flash an LED or
something, but I only need one half of it. I know unterminated inputs are
anathema for digital chips, but what about the spare half of a 556? From
the schem. on the data sheet,

it kinda looks like pulling them to either rail might be not too good for
the chip - what do you guys recommend?
Thanks!
