(1) All typical values are at 25°C and with a 3.3-V supply.
(2) t_sk(o) is the magnitude of the difference in propagation delay times between any specified terminals of channel 2 to 4 of a device when
inputs are tied together.
(3) t_sk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of channel 2 to 4 of two devices, or
between channel 1 of two devices, when both devices operate with the same source, the same supply voltages, at the same
temperature, and have identical packages and test circuits.
(4) The typical value is ensured by simulation.
