† _{All typical values are at VCC = 3.3 V (unless otherwise noted), TA = 25°C.}
‡ _{VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.}
§ _{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 TTL voltage level, rather than VCC or GND.}
# _{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.
