8. Applies to noncascaded/nonsynchronous clocked configurations only with synchronously cascaded counters. (1) Clock to Ripple Carry Out
propagation delays. (2) Enable T or Enable P to Clock setup times and (3) Clock to Enable T or Enable P hold times determine fmax. However,
if Ripple Carry out of each stage is tied to the Clock of the next stage (nonsynchronously clocked) the fmax in the table above is applicable.
See Applications information in this data sheet.
9. For propagation delays with loads other than 50 pF, and information on typical parametric values, see the ON Semiconductor High−Speed
CMOS Data Book (DL129/D).
