[2]

This is the increase in supply current for each input that is at the specified TTL voltage level rather than V

or GND.

[3]

Measured by the voltage drop between the nAn and the nBn terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (nAn or nBn) terminals.

10. Dynamic characteristics

[1]

The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).
