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. 3 PS8453F 03/09/01 PI3C32160 3.3V, High Bandwidth, 16:32-Bit, PCI Hot-Plug Mux/Demux Bus Switch 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 56-Pin TSSOP (A) Package 56 .236 .244 1 .547 .555 6.0 6.2 13.9 14.1 1.20 .047 Max.

For example, given a +3.3V supply, the output enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing Proper power-supply sequencing is recommended for all CMOS devices. It is recommended to always apply VCC before applying signals to input/output or control pins. Hot Insertion For Datacom and Telecom applications that have 10 or more volts passing through the backplane or system bus, a high voltage from the power supply may be seen at the device input pins during Hot Insertion. The PI3Cxxx devices have maximum limits of 5.5V and 120mA for 20ns. If the power is higher or applied for a longer period of time or repeatedly reaches the maximum limits, the devices can be damage.
