[1] This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON-state resistance of the

switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).

[2] tpd is the same as tPHL and tPLH.

[3] ten is the same as tPZH and tPZL.

[4] tdis is the same as tPHZ and tPLZ
