† 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).

‡ tPZL and tPZH are the same as ten.

§ tPLZ and tPHZ are the same as tdis.
