(1) All typical values are at V_CC = 3.3 V (unless otherwise noted), T_A = 25°C.
(2) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V_CC or GND.
(3) Measured by the voltage drop between 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.

(1) The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load
capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
