From Up/Down, Binary/Decade, Carry In or Preset Enable Control Inputs to Clock Edge

** If more than one unit is cascated in the parallel clocked application tr should be made less than or equal to the sum of the fixed propagation

delay at 15 pF and the transition time of the carry output driving stage for the estimated capacitance load.

*** From Carry in to Clock Edge.
