(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; 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 frequency.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; VI = GND to 3 V.
Fig.7
Waveforms showing the master reset
(MR) pulse width, the master reset to output
(Qn) propagation delays and the master
reset to clock (CP) removal time
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 = 1.3V; VI = GND to 3 V.

and hold times for J, K and Dn inputs.
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 = 1.3V; VI = GND to 3 V.

times from the parallel enable input
(PE) to the clock (CP).
