(1) VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.
(2) All typical values are at VCC = 5 V (unless otherwise noted), TA = 25°C.
(3) For I/O ports, the parameter IOZ includes the input leakage current.
(4) This is the increase in supply current for each input that is at the specified voltage level, rather than VCC or GND
(5) 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.

(1) 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).
