• Manufacturer: ONSEMI [ON Semiconductor]

NOTE: Information on typical parametric values can be found in Chapter 2 of the ON Semiconductor High–Speed CMOS Data Book
NOTE: For propagation delays with loads other than 50 pF, and information on typical parametric values, see Chapter 2 of the ON
* For T A = 25 C and C L = 50 pF, typical propagation delay from Clock to other Q outputs may be calculated with the following equations:
* Used to determine the no–load dynamic power consumption: P D = C PD V CC 2 f + I CC V CC . For load considerations, see Chapter 2 of the
