How about this?\n\nUnfortunately the server doesn’t allow me to post links yet. But I believe you will be able to find the datasheet (google for it). You do not need to believe me or not, just look at the datasheet, and if you can read them, you will see. It’s on the page 4 in the section “AC characteristics”.\nIf you can not, google “how to read the data sheets of components”.\n\nThis is strange indeed, didn't you read my earlier post#57 in which I included a link to the data sheet of that chip? Of course I read it, every page of it, including all the graphs.:D There is no need for you to re-link it, but it never hurts..
