VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.

† All typical values are at VCC = 5 V (unless otherwise noted), TA = 25°C.

‡ For I/O ports, the parameter IOZ includes the input leakage current.

§ This is the increase in supply current for each input that is at the specified 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).
