All typical values are at 25°C and with a 3.3-V supply.

tsk(p) is the magnitude of the time difference between tPLH and tPHL of a specified terminal.
(3)
tsk(o) is the magnitude of the difference in propagation delay times between any specified terminals of a sink-port bank when inputs of
the active source port are tied together.
