DYNAMIC ELECTRICAL CHARACTERISTICS (T
(*) Typical temperature coefficient for all V
(1) Time required after the falling edge of the reset or preset enable inputs before the rising edge of the clock will trigger the counter (similar
to setup time)
(2) If more than unit is cascaded 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 time of the carry output driving stage for the estimated capacitive load.
