--- Deleted the sentence about CDS examples, because the adopted IEC standard does not give examples later (see Chapter 4 of the:2007 edition);

--- Deleted all references to "IEC Q" and "QC";

--- Added "or rise time" and "or fall time" (see Table 3 and Table 6);

--- For the limit values of dimensions, "see Chapter 1" is changed to "see the summary page of Chapter 4 [7]" (see Tables 5 and 6, Chapter 8 of the:2007 edition):
