Stacking Buffers on a Pimeta (Tangent's layout)

[silvalis]

Since Tangent's Pimeta layout has pads for both SMD and the DIP8 buffers, is it possible (is there enough space) to stack buffers by soldering down an SMD BUF634, inserting a wirewrap DIP8 socket then popping in a DIP8 buffer?

Not recommended since the smd and dip versions do not operate the same as in output the same current when powered.

I was more thinking about a 2nd SMD buffer mounted on a browndog adaptor (I can't seem to find DIP8 buf634s)

I've used both on the same board without any problems.

So far as space goes, the SMD pads are on the back of the PCB, so there is no space issue at all unless you were trying to mount the board in a very shallow case (like a Serpac H65), in which case I don't know if the rear-PCB mounting of the SO8 would raise the board up too much, be problematic in that scenario.
