(1) Timerequired after the falling edge of the reset or preset enable inuts before the rising edge ofthe clock will trigger the counter (similar to setup time).
(2) Ifmore than unit is cascated in the parallel clocked application, trCL should be made less than or equal to the sum of the fixed propagation delay at
15pF and the transition timeof the carry output driving stage ofthe estimated capacitive load.
