3.3V , Quad 2:1 Mux/DeMux NanoSwitch™ Notes: For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. T ypical values are at VCC = 3.3V , +25°C ambient. Per TTL driven input (control inputs only); I and Y pins do not contribute to ICC. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The I and Y inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design. Notes: 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 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 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.

3.3V , Quad 2:1 Mux/DeMux NanoSwitch™ 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. Power-Supply Sequencing and Hot-Plug Information Proper power-supply sequencing is recommended for all CMOS devices. Always apply V CC and GND before applying signals to input/output or control pins. Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
