Why? Is it just the bulk lead capacitance, or is
there some other way
in which a DIP package is electrically deficient?
Back in the ECL 100K days, going from a DIP to a flatpack would shave 200
ps. This mattered a great deal back then. Of course now, everything works
at 100K speeds.
They also made for less "bumps" in the transmission line aspects of the
traces. Not a big difference, but enough to think about.
