Semiconductor High–Speed CMOS Data Book (DL129/D).
* For TA = 25°C and CL = 50 pF, typical propagation delay from Clock to other Q outputs may be calculated with the following equations:
VCC = 2.0 V: tP = [93.7 + 59.3 (n–1)] ns
VCC = 4.5 V: tP = [30.25 + 14.6 (n–1)] ns
VCC = 3.0 V: tP = [61.5+ 34.4 (n–1)] ns
VCC = 6.0 V: tP = [24.4 + 12 (n–1)] ns
Typical @ 25°C, VCC = 5.0 V

* Used to determine the no–load dynamic power consumption: PD = CPD VCC2f + ICC VCC. For load considerations, see Chapter 2 of the
