† _{All typical values are at VCC = 5 V (unless otherwise noted), TA = 25°C.}
‡ _{VO(USP) = A-port undershoot static protection.}
§ _{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.
