This parameter specifies the dynamic power-supply current associated with the operating frequency of a single control input (see

Figure 2).

(6)

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.

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).
