D 5 out dividing signal output terminal outputs dividing signal. D 6 n1 7 n2 dividing ratio selecting control terminal these inputs control the selection of a dividing ratio among 1 / 1, 1 / 2, 1 / 4, and 1 / 8. fm in terminal is selected at n1 = n2 = "l" level (1 / 1 dividing). the truth table is shown below. D 8 bias bias terminal connects capacitors on bias circuit. change this pin to low to convert the ic is to stand ? by mode.
