Product specification
74HC/HCT109
The shaded areas indicate when the
input is permitted to change for
predictable output performance.
Fig.6 Waveforms showing the clock (nCP) to output (nQ, nQ) propagation delays, the clock pulse width, the nJ,
nK to nCP set-up, the nCP to nJ, nK hold times, the output transition times and the maximum clock pulse
frequency.
