(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 frequency.

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

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

Fig.7 Waveforms showing the 3-state enable and disable times.

The shaded areas indicate when the input is

permitted to change for predictable output

performance.
