(1) All typical values are at 25°C and with a 3.3-V supply.
(2) t
sk(o)
is the magnitude of the time difference between the t
PLH
or t
PHL
of all receivers of a single device with all of their inputs driven
together.
(3) t
sk(pp)
is the magnitude of the time difference in propagation delay times between any specified terminals of two devices when both
devices operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
