CC
= 3.3 V.
[2] t
sk(o)
is the skew between specified outputs of a single device with all driving inputs connected together and the outputs switching in the
same direction while driving identical specified loads.
[3] t
sk(p-p)
is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices
operate with the same supply voltages, same temperature, and have identical packages and test circuits.
[4] Guaranteed by design and characterization.
