Waveforms showing the clock (CP) to output

(Qn) propagation delays, the clock pulse

width, the output transition times and the

maximum clock pulses frequency.

(1) HC : VM = 50%; VI = GND to VCC.

HCT : VM = 1.3 V; 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.

(1) HC : VM = 50%; VI = GND to VCC.

HCT : VM = 1.3 V; VI = GND to 3 V.

The shaded areas indicate when the input is permitted to

change for predictable output performance
