Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V
3. Per driven input (control input only); A and B pins do not contribute to I
Switching Characteristics over 3.3V Operating Range
Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
Power Supply Characteristics
Switching Characteristics over 2.5V Operating Range
P
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 timesof
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.
