All typical values are at VCC = 5 V, TA = 25°C.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
§ 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).
