AC WAVEFORMS
Fig.6
The clock (nCP) to output (nQ, nQ) propagation delays, the clock pulse width, the nD to nCP set-up, the
nCP to nD hold times, the output transition times and the maximum clock pulse frequency.
The shaded areas indicate when the input is permitted to change for predictable output performance.
