(1) tpd is the slower of tPLH or tPHL. The propagation delay is 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 impednace).
(2) ten is the slower of tPZL or tPZH.
(3) tdis is the slower of tPLZ or tPHZ.
