Preliminary Data Sheet
Clock Test Conditions
Clock timing and switching characteristics are specified in accordance with operating
conditions shown in the table “Recommended DC Operating Conditions.” AC
specifications are characterized with VDD = 1.5V, TC = +95 °C and a 10pF test load as
shown in the figure to the right.
