A signal is valid if it is above VIH or below VIL and invalid if it is between VIL and VIH.For the purpose of this specification the
following conditions apply (see Fig. 8):
a) All input signal are defined as: VIL = 0.2VCCIO, VIH = 0.8VCCIO, tR < 10ns, tF < 10ns.
b) Delay times are measured from the inputs signal valid to the output signal valid.
c) Setup times are measured from the data input valid to the clock input invalid.
d) Hold times are measured from the clock signal valid to the data input invalid.
