(2) The propagation delay is the calculated RC time constant of the typical ON-State resistance of the switch and the specified load
capacitance when driven by an ideal voltage source (zero output impedance).
(3) Output skew between center port (A

) and any other channel.
(4) Skew between opposite transitions of the same output |t
