Odd. The TI databooks I've looked in (both
versions) show the _same_
function table for the '123 and 'LS123 (and the older edition includes
the 'L123 in the same table). All devices claim to trigger on a rising
edge of clear under the specified conditions. The Philips databook I have
only lists the '123, and yes, it is claimed to trigger that way too.
This was Fairchild application notes. Something I found on the web.
I will admit I've not tried it, in fact I try to
avoid using monostables.
So either the databooks are wrong (which is entirely possible), or this
is a manufacturer-specific thing.
I think National may also be the same.
