[1] This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON
resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance).
[2] t_PLH and t_PHL are the same as t_pd.
t_PZL and t_PZH are the same as t_en.
t_PLZ and t_PHZ are the same as t_dis.

Measurement points are given in Table 8.
V_OL and V_OH are typical voltage output levels that occur with the output load.
