Notes:

1.

This parameter is guaranteed but not tested on Propagation Delays.

2.

The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The switch’s time constant

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 propaga-

tional 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.

Applications Information

Logic Inputs

The logic control inputs can be driven up to +3.6V regardless 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® minimizes power consumption.
