Posting links to data sheets may encourage increased crowd sourced solution non-finding. Or not. http://www.nxp.com/documents/data_sheet/74LVC1G53.pdf http://www.nxp.com/documents/data_sheet/74LVC2G53.pdf A flicker comparator check of all pages of the two data sheets indicated that the only obvious (to me) differences were in formatting of data or rearrangement of the position of a few tables and diagrams. The similarities and in most cases complete identicality suggests that the x1x sheet was a final proof copy and the x2x sheet is the final version. On page 11 (both cases) the text "load circuit" has been changed to "test circuit" That appears to be about the most significant [tm] change in actual content= !
