1. For a given set of conditions (i.e., capacitive load, temperature and VCC) the variation from device to device is guaranteed to be less than or
equal to the maximum.
2. Where tp Qn and tp Qm are the actual propagation delays (any combination of HIGH or LOW) for any two separate outputs from a given high
transition of CLK.
