This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined

by the lower of the voltages of the two (A or B) terminals.

NOTE:

1. 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).
