(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
PHL
or t
PLH
of all receivers of a single device with all of their inputs connected
together.
(3) t
sk(pp)
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, at the same temperature, and have identical packages and test circuits.
