Notes
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V DD = 3.3V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between Y and In pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the
two (Y, In) pins.
5. This parameter is determined by device characterization but is not production tested.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. 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.

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, 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 VDD before applying signals to the input/
output or control pins.
