(1) Maximum switching frequency for control input (V_O > V_CC, V_I = 5 V, R_L ≥ 1 MΩ, C_L = 0)
(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).
