Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V re gard less of the supply voltage. For example, given a + 3.3V supply, IN may be
driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail
Power-Supply Sequencing and Hot-Plug In for ma tion
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V
input/output or control pins.

Parameters
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.
