AC WAVEFORMS
Fig.8
Waveforms showing the clock (CP) to outputs (Qn, TC) 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.9
Waveforms showing the master reset (MR) pulse width, the master reset to output (Qn, TC) propagation
delays and the master reset to clock (CP) removal time.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.10 Waveforms showing the input (CET) to output (TC) propagation delays and output transition times.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
