Well, so I mount them on the opposite surface. :-) [description of SMD deleted] There are two things which fit this description which are visible if I look into the Sam's floppy (an HC00 and an HC03 if I remember correctly). I presume these are they. > PS re 74, HC374 & HC574 they are functionally the same! BUT their D->Q pinout > is totally different.. next time look at the pinouts first;-) According to my Maplin catalogue they have identical pinouts. Unfortunately the catalogue doesn't say whether they have buffered outputs or not and doesn't give the output characteristics either. imc
