2. Active power represents normal data communication. Standby power is when the device is enabled for operation but there is no LAN traffic
(cable not connected). Power down current is the minimum power state used when not connected and mobile.
3. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the lower
of the voltages on the two (A & B) pins.
4. Guaranteed by design and/or characterization.
5. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance.
The time constant for the switch alone is of the order of 0.25 ns for 10 pF load. Since this time constant is much smaller than the rise/fall
times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in
a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
