(2)

This is the increase in supply current for each input that is at the specified voltage level, rather than VCC or GND.

(3)

Measured by the voltage drop between the A and the 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).
