Of course manufacturers don't want to use DIPs.
They are electrically
inferior. For that matter, they are also obsolete -- if they made DIP
packaged chips they would certainly be very low volume products.
I understand the preference for DIPs in amateur work, though SMT isn't
really all that hard. But I can't imagine any reason for wanting DIPs
in new commercial designs. They are bigger, slower, not RoHS
compliant, ...
I just want PLCC packaging and 5 volt logic. I keep looking at all the
new FPGA logic
thinking that would be a nice chip and I don't like the packaging or
voltage.Also with all
the new chips you get more pins, but more of them are power.

Also all my designs are nice and slow LS speeds.That is not to say I may
not go faster
but right now slow I/O devices are the factor for me.
PS. BG. Micro also has some nice heat sinks just in case you need them
for a linear power
supply,
