The switch contributes no propaation 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 0.30ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical drivin sinals, it adds very little propaation delay to the system. Propaation delay of the switch when used in a system is determined by the drivin circuit on the drivin side of the switch and its interaction with the load on the driven side.

For example, iven a +3.3V supply, EN may be driven LOW to 0V and HIGH to 3.6V. Drivin EN Rail-to-Rail minimizes power consumption. Hot Insertion For Datacom and Telecom applications that have ten or more volts passin throuh the backplane, a hih voltae from the power supply may be seen at the device input pins durin hot insertion. The PI3CH400 devices have maximum limits of 6V and 120mA for 20ns. If the power is hiher or applied for a loner time or repeatedly reaches the maximum limits, the devices can be damaed.
