(1)All typical values are at 25

C and with a 3.3-V supply.
(2)tsk(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.
