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

or GND.
§
Measured by the voltage drop between the input terminal and the output terminal at the indicated current through the switch. On-state resistance
is determined by the lowest voltage 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).
