These are a little larger than what I was thinking of but were
mentioned the other day in funwithtubes at yahoogroups.com and are
probable more suitable for most projects anyway:

>>Your comments on layout made me think again of how to implement these projects.  How do you use a 14 pin SMD IC?  I could try to connect it with flying leads but I'd like something better.  Is there some kind of socket for these devices?  Or a generic board to receive such things?
