AC WAVEFORMS
Fig.7
Waveforms showing the clock (CP) to
output (Q
n
) propagation delays, the clock
pulse width, the output transition times and
the maximum clock frequency.
(1) HC : V
M
= 50%; V
I
= GND to V
.
HCT: V
M
= 1.3 V; V
I
= GND to 3 V.
Fig.8
Waveforms showing the master reset (MR)
pulse width, the master reset to output (Q
n
)
propagation delays and the master reset to
clock (CP) removal time.
(1) HC : V
M
= 50%; V
I
= GND to V
.
HCT: V
M
= 1.3 V; V
I
= GND to 3 V.
Fig.9
Waveforms showing the set-up and hold
times from the data inputs (D
n
, D
SR
and
D
SL
) to the clock (CP).
The shaded areas indicate when the input is permitted to
change for predictable output performance.
