tPLH and tPHL are the same as tpd. 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).

(2)

tPZL and tPZH are the same as ten.

(3)

tPLZ and tPHZ are the same as tdis.
