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

driven by an ideal voltage source (zero output impedance).
