(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
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 input (CET) to output (TC) propagation delays and output transition times.
The shaded areas indicate when the input is
permitted to change for predictable output
performance.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.10 Waveforms showing the set-up and hold times for the input (Dn) and parallel enable input (PE).
