Product specification
74HC/HCT564
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.6
Waveforms showing the clock (CP) to
output (Qn) propagation delays, the clock
pulse width, the output transition times and
the maximum clock pulse frequency.
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.7 Waveforms showing the data set-up and
hold times for the data input (Dn).
