You need to give me at least TWO tries for all of my postings. Up to
FOUR if I've been drinking.

(I hit post instead of cancel after deciding it would be a good idea to
actually check the datasheet for the part in question before posting.
Thus the incomplete sentence. See followup about the specs for the
entire LC product line. )

Don't you hate it when the product sheet says something different than what
