NOTES:
1. For propagation delays with loads other than 50 pF, see Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).
2. Information on typical parametric values can be found in Chapter 2 of the Motorola 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 = [205 + 100(N – 1)] ns
VCC = 4.5 V: tP = [41 + 20(N – 1)] ns
VCC = 6.0 V: tP = [35 + 17(N – 1)] ns
