Notes:
1. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
2. This parameter is determined by device characterization but is not production tested.
3. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined
by the lower of the voltages on the two (A,B) pins.

Note:
1. This parameter is guaranteed but not tested on Propagation Delays. 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 0.25ns for 50pF 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 interaction with the load on the driven side.
2. See test circuit and waveforms.
