Hi Brian,

Would that be similar to the Sharp PC-817(I) series? They also "specify" an SO-4 package...but their data sheet clearly shows
TH patterns.  I ended up creating one from scratch using WindRiver's landpattern calculator spreadsheet.  I could send you the
PDF of Sharp's spec. off-list if you want.
