Corrected a Table 1 typogaraphical error, it listed tpLH MR to Qn, it should be tpHL MR to Qn. Changed note 5 (guaranteed, not tested) in the AC (50pF) notes column to note 2 (Screen tested 100% at +25C, subgroup 9) & to note 4 (Sample tested at +25C, subgroup 9, Subgroups 10 & 11 are guaranteed not tested). Changed note 2 in the AC (15pF) notes reference column to note 5. Reworded the phrase in note 4 from 'and periodically at +125C & -55C, subgroups 10 & 11' to "Subgroups 10 & 11 are guaranteed, not tested'. 6
