The 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 0.30ns for 10pF 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 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. 4 PS8760 02/01/05 PI3USB14 Low Voltage, High Bandwidth, USB 2.0, 4:1 Mux/DeMux with Single Enable Test Circuit for Electrical Characteristics(1) 6.0V VCC 200-ohm Pulse Generator VIN VOUT D.U.T 10pF CL RT 200-ohm Notes: 1.

For example, given a +3.3V supply, EN maybe driven LOW to 0V and HIGH to 3.6V. Driving EN Rail-to-Rail® minimizes power consumption. Power Supply-Sequencing Proper power supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/ output or control pins. Hot Insertion For Datacom and Telecom applications that have ten or more volts passing through the backplane, a high voltage from the power supply may be seen at the device input pins during hot insertion. The PI3CHxx devices have maximum limits of 6V and 120mA for 20ns. If the power is higher or applied for a longer time or repeatedly reaches the maximum limits, the devices can be damaged.
