Fig.6
Waveforms showing the clock (nCPn) to output (nQn) propagation delays, the clock pulse width, the output
transition times and the maximum clock frequency.
(1) HC : VM = 50%; VI = GND to VCC.
HCT : VM = 1.3 V; VI = GND to 3 V.
Fig.7
Waveforms showing the master reset (nMR) pulse width, the master reset to output (nQn) propagation
delays and the master reset to clock (nCPn) removal time.
(1) HC : VM = 50%; VI = GND to VCC.
HCT : VM = 1.3 V; VI = GND to 3 V.
