AC WAVEFORMS

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).
