AC WAVEFORMS
Fig.6
Waveforms showing the clock (CP) to output
(Qn) propagation delays, the clock pulse
width, the output transition times and the
maximum clock pulses frequency.

HC : VM = 50%; VI = GND to VCC.
HCT : VM = 1.3 V; VI = GND to 3 V.
Fig.7
Waveforms showing the master reset (MR)
pulse width, the master reset to output (Qn)
propagation delays and the master reset to
clock (CP) removal time.

HC : VM = 50%; VI = GND to VCC.
HCT : VM = 1.3 V; VI = GND to 3 V.
Fig.8 Waveforms showing the data set-up and hold times for the data input (Dn).
The shaded areas indicate when the input is permitted to
change for predictable output performance
